Compensation Problem

Pp. 197-229 (33)

Boris Levin


Issues of applying the compensation method application are studied, including the heterogeneous nature of the media, optimal placement of main and auxiliary radiators, the dark spot dimensions, the reduction factor and variation of the total and local SAR, retention of patterns and field strength. Results of calculations, performed by different methods, are compared with each other and with experiment. A technique of protecting system against external action is described; the automatic adjustment circuit is developed. Recommendations for using the compensation method in a wide frequency range are given.
