Abstract

A novel ultra wideband microwave system based on finite difference time domain was investigated for detecting early breast tumor. Using published data for the dielectric properties of normal breast tissues and malignant tumors, a three dimensional (3-D) computational electromagnetics analysis of the system was conduced. And the effects of medium's absorption, reflection and refraction on the border of two mediums were taken into account. The confocal microwave imaging results attest the simulation's validity. Tumors can be robustly detected and distinguished from the surrounding normal tissues.
