Antenna theory

My interests in antenna theory are on modeling, physical bounds, and understanding of single port as well as MIMO and UWB antennas, see the projects physical bounds in antenna theory and MIMO antennas and channels. Physical bounds on D/Q and Q are computed by AntennaQ.m

Scattering theory

My research in scattering theory is focused on modeling and understanding of electromagnetic scattering. It involves physical bounds on scatterers, such as metamaterials, shadow scattering (or the extinction paradox), and extraordinary transmission through sub wavelengths apertures.

Project: physical bounds in electromagnetic theory.

Digital holography

See the project digital holographic imaging and the company Phase holographic imaging AB.

Inverse scattering

My research in inverse scattering is focused on time domain algorithms, resolution analysis, and to analyze the information content in inverse scattering data, see the project on microwave tomography.
