About Us

Our group, the Center for Electromagnetic Theory and Applications (CETA) at MIT, led by Prof. J. A. Kong, has an extensive background in theoretical and numerical electromagnetics, remote sensing, propagation of electromagnetic waves in complex media, and electromagnetic modeling in general. Recently, our activities have been concentrated on modeling optical tweezers and other known optical trapping systems for spherical and cylindrical dielectric particles. Although the experimental part of this work is being actively developed in various groups, the theoretical modeling of these systems still seems at its infancy.

Our recent activities include:
