Computational Electromagnetics (methods and commercial tools)

QUICNEC (QUasi-static Inductive Capacitive Numerical Electromagnetics Code) -This code is used to model thin-wire antennas with geometrically complex quasi-static regions.

Spectral Domain Immittance Functions - These functions are used to model the interaction between multiple printed antennas in stratified anisotropic dielectrics

HFSS (High Frequency Structure Simulator) by Ansoft - Commercial full-wave 3D EM solver.

ADS 2009 (Advanced Design System) by Agilent - Commercial full-wave EM solver.

Electromagnetic compatibility issues with metamaterial based transmission lines (i.e. radiation and coupling between metamaterial based multi-conductor transmission lines.)

Adaptive (smart) arrays integrated on system-on-a-chip and IC packages for wireless applications (Future work)
