Abstract :
By analyzing and optimizing acoustic and electromagnetic waves absorption in a simplified layered model of hyperthermic configuration, it is shown that the commonly used attenuation metrics are not always proper means for determining the generally optimal parameters of typical thermal therapy problem with finite extent target The conditions, parameters and bounds for optimal (maximal) incident power absorption for the layered model have been found analytically and explicitly and are presented in terms of basic wave propagation characteristics, thus, also providing the necessary data for optimal synthesis of absorbing tissues and materials.
