Events Presented Events Feb 20 - Feb 26, 2022 Multi-physics Simulation of Plasmonic Photoconductive Devices and Antennas Hakan Bagci, Associate Dean for Students, Computer, Electrical and Mathematical Sciences and Engineering Feb 20, 12:00 - 13:00 B9 L2 R2322 H1 Multiphysics Simulation Terahertz (THz) frequency electromagnetic fields have numerous applications ranging from wireless communications to imaging systems and nondestructive testing, to material characterization. One of the main obstacles in the way of widespread industrial use of THz technologies is the difficulty of implementing compact and frequency-stable THz sources that can operate at room temperatures. Among a variety of possible options, photoconductive devices (PCDs) satisfy these conditions. Indeed, they have become one of the most promising candidates for THz source generation since recent advances in fabrication techniques, such as metasurface integration and nanostructured surface inclusions have significantly increased their optical-to-THz conversion efficiency and made them polarization insensitive. Sep 26 - Oct 2, 2021 Accurate and Efficient Methods to Simulate Electromagnetic Systems Hakan Bagci, Associate Dean for Students, Computer, Electrical and Mathematical Sciences and Engineering Sep 28, 16:00 - 17:30 B9 L2 R2322 Simulation tools are often enablers of cutting-edge research in many fields of science and engineering. This also applies to the field of electromagnetics: Design and characterization of many electromagnetic systems and devices, which drive technological advances in areas such as communications, computing, biomedicine, and solar energy, would not be possible without simulation tools. Having said that, developing numerical methods for electromagnetic analysis of such complex systems is not a trivial task. Dimensions of these systems are large (longer than several wavelengths), their frequency of operation has a wide range, and their geometry has sub-wavelength features. When it comes to simulating these systems by solving the Maxwell equations (in differential or integral form), these characteristics translate into multiscale discretizations, large and often ill-conditioned matrix systems with millions of unknowns to be solved for, and long execution times. My research group at KAUST has been developing efficient, accurate, and robust electromagnetic solvers to address these challenges. In this talk, I will provide an overview of my group’s recent research activities. Technical part of my presentation will focus on two examples, where I talk about solvers we have developed to efficiently and accurately simulate photoconductive antennas (used in terahertz source generation) and plasmonic structures (with a wide range of applications from sensing to solar energy). I will provide results that demonstrate the benefits of these solvers over existing methods. I will conclude my talk with a brief description of my future research plans and a few slides about my research supervision, teaching activities, and international visibility of my research group.
