Abstract :
A spatial distribution of radiometer input transfer function in a three-layered human body is calculated by the numerical finite-difference time domain method. The examples for different radiometer input parameters and measurement methods are calculated and examined by experiment. The results of numerical modelling are applied for design of a 4.5 GHz microwave radiometer for breast cancer detection
