Tomasz M. Grzegorczyk received his Ph.D. degree from the Laboratoire d'Electromagnetisme et d'Acoustique (LEMA), Ecole Polytechnique Federale de Lausanne (Swiss Federal Institute of Technology, Lausanne) in December 2000. In January 2001, he joined the Research Laboratory of Electronics (RLE), Massachusetts Institute of Technology (MIT), USA, where he is now a research scientist. His research interests include the study of wave propagation in bianisotropic media and left-handed metamaterials, electromagnetic induction from spheroidal object for unexploded ordnances modeling, and optical binding and trapping. He is a member of IEEE, has been a Visiting Scientist at the Institute of Mathematical Studies at the National University of Singapore, and has been appointed as Adjunct Professor of The Electromagnetics Academy at Zheijiang Universtity in Hangzhou, China, in July 2004. Since 2001, he is part of the Technical Program Committee of the Progress in Electromagnetics Research Symposium and of the Editorial Board of the Journal of Electromagnetic Waves and Applications.

• May 2003 -- Present (research scientist)

Center for Electromagnetic Theory and Applications ( CETA )

Massachusetts Institute of Technology ( MIT ), USA


Optical binding and trapping:
Theoretical modeling of optical matter, interaction between particles submitted to laser illumination, design of a laser trapped mirror. These studies involve advanced electromagnetic modeling of interaction between particles, including all interactions and depolarization effects using the coherent Foldy-Lax multiple scattering equations. The optical forces are evaluated using the Maxwell stress tensor or bound charges and currents.

Study of wave propagation in complex media including left-handed metamaterials:
Fundamental theoretical aspects of electromagnetics in isotropic, anisotropic, bianisotropic media having arbitrary sign of permittivity and permeability; Mathematical inversion of constitutive paramters of uniaxial, biaxial and general bianisotropic (72 unknown parameters) media; Moving left-handed media; Numerical modeling (MoM, FDTD) of split-rings and rods; Applications using left-handed metamaterials.

Polarimetric study of ocean and forest and wave propagation over rough terrains :
Integral equation formulation of multilayered rough surfaces; Fast algorithms for the computation of the scattering coefficients; Passive remote sensing of ocean surfaces.

Electromagnetic induction from spheroidal object for unexploded ordnances modeling:
Forward models using a spheroidal mode approach; inverse models using analytical inversions as well as genetic algorithms and support vector machine. FEM modeling of bodies of revolution and time domain response in the electromagnetic induction regime (low frequencies).

Miscellaneous:
Signal processing for SAR systems, space-time adaptative processing (STAP) for ground moving target indicators (GMTI) and air-borne moving target indicators (AMTI).
