Study of superposition of SAR distribution created by external and interstitial applicator

This paper deals with a study of the shapes of SAR distribution created by a superposition of EM expositions done contemporary by external and interstitial applicator. Three different cases are numerically and experimentally studied and compared in this paper. In the first case we describe the shape of SAR distribution created only by monopole antenna, which represents interstitial applicator. In the second case we discuss the SAR distribution created only by external microwave stripline type applicator with TEM mode. In the last case we describe a superposition of SAR distribution created by EM expositions done contemporary by external and interstitial applicator. Both applicators are excited at the same frequency (f = 434 MHz), power and phase. Numerical results of SAR distribution are compared with those obtained experimentally for all three cases, very good correlation between simulations and measurements can be seen.
