New computational model of electromagnetic field distribution for predicting of the safety zones in the near-field of microwave antennas

Abstract

A new program of evaluation of the electromagnetic field strength distribution has been presented. This program has been mainly designed for calculating the area of safety zones around microwave antennas. New expressions of the E and H fields by modifying vector potentials have been derived. The received formulas allow the calculation of the EM field distribution in the near-field. The calculation program can be used for a wide class of microwave antennas, like GSM or radar antennas. The real topography of the ground is included for calculation of the incident, reflected and resultant rays.
