Continuous and digital modulated radiofrequency fields propagation in planar biological models

The aim of the study is a comparison between continuous and digital modulated radiofrequency fields absorption in planar biological models. Results obtained show that specific absorption rate attenuation with depth and its distribution, for continuous wave and for the modulated signals, depend on the signal parameters, on the dielectric characteristics of the layers and on the thickness of the layers. The method allows a theoretical prediction of the radiofrequency power distribution of different radiofrequency signals in biological targets.
