Speaker: Assoc. Prof. Alpan Bek, Middle East Technical University

Topic: “High Resolution Optical Microscopy and Spectroscopy Techniques in Biology”

Location: Middle East Technical University, Ankara, Turkey

Abstract:  High resolution optical microscopy and spectroscopy used to be limited in the micrometer spatial resolution for about 3 centuries after development of the first microscopes in 17th century. The limiting factor behind such a long time of further advancement has ultimately  been the diffraction limit of visible light. It was in late 20th century when technology has finally advanced beyond the limitation of diffraction to enable optical spatial resolution down to the nanometer. Nanometer dimension is the realm of large molecules of which maybe most interesting ones such as proteins are of biological origin. In this talk I will present the ideas behind breaking the diffraction limit and give an overview of several high resolution imaging and spectroscopy techniques in biological specimen analysis.

12 May 2017 (13:40):  IEEE AP/MTT/EMC/ED Turkey 2017 Seminar Series (S.11)

Speaker: Prof. Vakur B. Ertürk, Bilkent University

Topic: “Incomplete-Leaf Multilevel Fast Multipole Algorithm for Multiscale Electromagnetics Problems”

Location: Middle East Technical University, Ankara, Turkey

Abstract: Fast Multipole Method (FMM) is selected as one of the 10 algorithms with the greatest influence on the development and practice of science and engineering in the 20th century, and its multilevel version, Multilevel Fast Multipole Algorithm (MLFMA), is currently among the most widely used and powerful methods in computational electromagnetics (CEM) in addition to its use in other fields such as chemistry, biology, and physics applications. However, when scattering from multi-scale (electromagnetic) applications are considered, for instance electrically small and structurally complicated antennas on large platforms, MLFMA may become considerably inefficient or inaccurate originating from the fact that it deploys fixed-size boxes at each and every level of the corresponding tree structure, which is not suited when use of a multi-scale meshing (i.e., highly nonuniform) is inevitable.  

In this talk, we will present our recent work on an efficient and versatile broadband MLFMA, which is capable of handling large multiscale electromagnetic problems with a wide dynamic range of mesh sizes. By invoking a novel concept of incomplete-leaf tree structures, where only the overcrowded boxes are divided into smaller ones for a given population threshold, versatility of using variable-sized boxes is achieved. Consequently, for geometries containing highly overmeshed local regions, the proposed method is always more efficient than the conventional MLFMA for the same accuracy, while it is always more accurate if the efficiency is comparable. Furthermore, in such a population-based clustering scenario, the error is controllable regardless of the number of levels.

5 May 2017 (13:40):  IEEE AP/MTT/EMC/ED Turkey 2017 Seminar Series (S.10)

Speaker: Assoc. Prof. Hüsnü Emrah Ünalan, Middle East Technical University

Topic: “Transparent Contacts With Metal Nanowire Networks”

Location: Middle East Technical University, Ankara, Turkey

Abstract: Figure of merit transparency and sheet resistance values of the metal nanowire networks are very close, if not better, than those of commercially available transparent and conducting thin films, such as indium tin oxide (ITO). In addition, nanowire networks carry the prominent advantage of solution processability. In this presentation, I will talk about our efforts on the utilization of silver (Ag) and copper (Cu) nanowire networks as transparent contacts for polymeric light emitting diodes, solar cells and transparent heaters. Following their synthesis and purification, nanowires are deposited onto various substrates in the form of networks through spray coating. Surface roughness and long-term stability of the networks are carefully monitored, where the latter is a particularly important problem for Cu nanowires. Infiltration of a conducting polymer decreased the roughness associated with the networks so that they can be used as anodes in polymeric light emitting diodes. In order to eliminate the shading losses associated with conventional screen-printed finger electrodes in single crystalline silicon solar cells, networks were utilized as top contacts. Through the application of a post-deposition treatment for the formation of the ohmic contacts, a relative enhancement in conversion efficiency of 21% was obtained with respect to the reference cells. When used as transparent heaters, reproducible heating characteristics and uniform temperature distribution was obtained from the networks. The effect of nanowire density on the temperature profile, applied voltage as well as turn on/off characteristics were investigated.

2 May 2017 (13:40):  IEEE AP/MTT/EMC/ED Turkey 2017 Seminar Series (S.9)

Speaker: Prof. Ibrahim Tekin, Sabancı University

Topic: “High Isolation Full Duplex Communication Antennas”

Location: Middle East Technical University, Ankara, Turkey

Abstract: Many technologies are being considered for efficient 5G communication. In-Band Full Duplex (IBFD) is one effective way to increase the spectral efficiency and the throughput of wireless communication systems by transmitting and receiving simultaneously on the same frequency band but the coupling (called Self Interference or SI) of transmit signal to its receiver is one major problem. IBFD operation can be realized successfully by suppressing this coupling or Self Interference (SI). The goal is to achieve high interport isolation for dual port antennas with minimum effect on radiation performance of antennas. In this talk, microstrip patch antennas which deploy different feeding techniques along with Self Interference Cancellation (SIC) circuits to get high interport isolation to enable such antennas for realization of IBFD wireless operation using single/shared antenna architecture will be presented.

28 April 2017 (13:40):  IEEE AP/MTT/EMC/ED Turkey 2017 Seminar Series (S.8)

Speaker: Prof. İrşadi Aksun, Koç University (Co-Author: H. Serhat Tetikol)

Topic: “Understanding Surface Plasmon Polaritons (SPP) via Critical Study of Dispersion Relation – Complete Picture and Correct Interpretation”

Location: Middle East Technical University, Ankara, Turkey

Abstract: Dispersion relation for surface plasmon polaritons (SPPs) is a fundamental equation that has long been known. A common misconception in its solution is that either a complex frequency or a complex wave-vector can be used to account for losses in the system. We show that both frequency and wave-vector should simultaneously take complex values in order to fully account for the underlying physics represented by the dispersion relation, resulting in Dispersion Surface. Realizing that the dispersion surface is in fact a manifestation of a richly embroidered set of dispersion lines, which may be accessible by carefully selecting source and material properties, our results pave the way for the possibility of unprecedented engineering of resolution, confinement, group velocity and band-gap in structures supporting SPPs. Our results are also applicable to a larger class of waves in dispersive environments, and pose a major amendment to the conventional interpretation of dispersion.

21 April 2017 (13:40):  IEEE AP/MTT/EMC/ED Turkey 2017 Seminar Series (S.7)

Speaker: Asst. Prof. Rohat Melik, TOBB-ETÜ

Topic: “Modulation of Ion Concentration In-Vivo”

Location: Middle East Technical University, Ankara, Turkey

Abstract: Our motion and behavior are as a result of the change of the cellular membrane potential. Therefore, by controlling the membrane potential in-vivo, we can control our motion and behavior. In our work, we applied extrinsic current and changed the ion concentration gradient in-vivo hence; changed the membrane potential in-vivo. Therefore, we proposed and developed two fundamental technologies: changing ion concentration gradient in-vivo and changing membrane potential in-vivo. We used these fundamental technologies for therapeutics of neurological disorders. Approximately 6 million people are paralysis in US (1.9%). Conventional Functional Electrical Stimulation (FES) aims to restore neurological functions such as standing, ambulation etc. However, there is no widely acceptable FES system because of high-energy expenditure and stimulation of nearby sensory nerves, causing pain. By using our novel electrochemical stimulation and blocking method, we modulated ion concentration around the sciatic nerve of a frog in-vivo using ion-selective membrane (ISM), hence; lowered the stimulation current therefore decreased the energy expenditure. We also lowered the blocking current as a result localized stimulation and reduced pain.

Speaker: Asst. Prof. Hüseyin Arda Ülkü, Gebze Technical University

Topic: “Quantum Corrected Plasmonic Field Analysis using Time Domain Surface Integral Equation Solvers

Location: Middle East Technical University, Ankara, Turkey

Abstract: When two structures are within sub-nanometer distance of each other, quantum tunneling effect becomes relevant. These effects cannot be accurately modeled by classical electromagnetic solvers. In this study, an auxiliary tunnel that connects the structures is introduced to model the quantum tunneling effect. The quantum model of the tunnel is obtained using density functional theory (DFT) computations, which account for the atomic structure of materials. The plasmonic fields on the resulting connected structure are analyzed using a time domain surface integral equation solver. Time domain samples of the dispersive medium Green function and the dielectric permittivities are computed from the analytical inverse Fourier transform applied to the rational function representation of their frequency domain samples. Numerical results, which demonstrate the effect of the quantum correction on the transient electromagnetic interactions, will be presented.

The solution for the field terms are determined in terms of infinite number of unknown coefficients which satisfy an infinite set of linear algebraic equations. These unknown coefficients are solved numerically and the effect of area ratio on the reflection coefficient is determined.
