Abstract

New approach to electromagnetic field calculations in the near-field of microwave antennas R. Kubacki 'I, M. Wnuk 2), W. Kolosowski 2), J.

A new program of evaluation of the electromagnetic field strength distribution has been presented. This program was designed mainly for E and H value calculations in the near-field to make an accurate assessment of the EM field exposure level for possible health hazard. New expressions of the E and H fields were derived by modifying vector potentials. The final formulas allow calculating the EM field distribution in the near-field as well as calculating the "safety zones" in the vicinity of microwave antennas. It is possible to use the received formulas for calculating the value of power density in the near field. The program of EM field distribution calculations can be used for a wid
