Research

My research interests are in scientific computing, specifically in the area of computational electromagnetics (EM). I have been mainly interested in the development of efficient time-domain computational engines and their application to complex engineering EM problems. I am also interested in the hybridization of EM simulators with other physics simulators.

I have worked on the development of fast and parallel integral equation solvers, FFT-based acceleration techniques, and a variety of hybrid simulators including finite-element/boundary-integral EM, full-wave EM/circuit, and full-wave EM/transmission-line simulators. These simulators have been used in a wide range of applications such as radar-cross-section characterization of aircrafts, EM interference/compatibility analysis of cable-interconnected electronic systems, design of nonlinear microwave circuits, modeling of on-chip and on-package interconnects, and radiation and coupling analysis of conformal antennas.
