Efficient Determination of the Near-Field in the Vicinity of an Antenna for the Estimation of Its Safety Perimeter
By
Progress In Electromagnetics Research, Vol. 103, 371-391, 2010
Abstract
The following paper deals with the problem of computing a safety perimeter, i.e., where the electromagnetic field due to a radiating system exceeds a certain electromagnetic value. The flexibility of the source reconstruction method (SRM) is employed to compute the fields almost everywhere around the antenna. Techniques for fast computing of the fields in the spectral and spatial domains exploiting the characteristics of the SRM are considered in order to avoid expensive integrations over the sources surface. Results for a logperiodic antenna and a base station antenna for cellular phone systems are shown, and compared with the usual far-field approximation.
