Electromagnetics and Antenna Research

Overview

Our antenna related research has been focused towards understanding the emission of electromagnetic radiation of atoms, an efficient electrically small antenna, and translating this knowledge to a macroscopic device. As shown in Microwave Optical Letters, vol. 25, pp. 95-101, 2000, radiation Q can be controlled through the relative phasing between different antenna elements. We have numerically and experimentally obtained radiation Q values for electrically small antennas a factor of twenty below the Chu limit established for omni-directional antennas.

Many of our antenna breakthroughs are published in the book by D. M. Grimes and C. A. Grimes, The Electromagnetic Origin of Quantum Theory and Light, World Scientific, Singapore, 2002, ISBN 981-02-4785-0. Click here to view some of the intriging real-time animation of power radiation.
