Ph.D. students Sadeed B. Sayed and Ismail E. Uysal working in the Computational Electromagnetics Group led by Prof. Hakan Bagci ranked 3rd and 5th in the student paper competition at the 30th International Conference on Review of Progress in Applied Computational Electromagnetics (ACES). Approximately 150 papers were accepted and they will appear on IEEE's webpage IEEE Xplore. Only 12 papers were selected as finalists in the student paper competition.
Sadeed's paper titled "Stable Quasi-Explicit MOT Solver for the Time Domain Volume Electric Field Integral Equation" describes a novel method for characterizing electromagnetic transients on inhomogeneous dielectric objects. The time-domain volume integral equation describing these interactions is cast in the form of an ordinary differential equation is solved using a PE(CE)m scheme. The resulting marching-on-in-time (MOT) scheme is quasi-explicit and the pertinent matrix system is sparse and well-conditioned regardless of the time step size. This ensures the efficiency of the solver even at low frequencies.
Ismail's paper titled "MOT Solution of the Time Domain PMCHWT Integral Equation for Lossy Dielectric Scatterers" describes a time-domain integral equation solver for analyzing transient scattering from lossy dielectric objects. Unlike existing methods, the proposed solver can be used on multiple and/or multilayered composite structures. This is achieved by introducing an additional temporal convolution to the retarded-time integrals. The discretization of this convolution is carried out with special care in order not to increase the computational cost of the resulting solver.
Sadeed received the Bachelor of Electronics and Communication Engineering from NITC, India in 2004. After completing the Masters in Communication Engineering from IITD, India in 2007, he worked as System Engineer in Digibee Microsystems. Later he joined Qualcomm India Pvt. Ltd in 2008, as a Firmware Engineer. Currently, he is with Computational Electromagnetics Laboratory at the King Abdullah University of Science and Technology (KAUST), pursuing his Ph.D. in Electrical Engineering. His research interest is in the field of time-domain volume integral equations for electromagnetics.
Ismail received the Bachelor of Science and Master of Science degrees in Physics from Koc University, Turkey in 2009 and 2011, respectively. Currently, he is with the Computational Electromagnetics Laboratory at the King Abdullah University of Science and Technology (KAUST), where he is pursuing his Ph.D. in Electrical Engineering. His current research interests include electromagnetic scattering properties of dispersive media and plasmonic structures.
