摘要: The distribution of the heating potential inside a lossy sphere having same electrical characteristics as those brain tissue was investigated in frequency region 10 MHz to 12 GHz. conditions under which hot spot appears and its shape were determined displayed radius vs. diagram. results show that spots appear only for spheres with radii 8 cm > R 0.1 range 300 < f 12,000 MHz. It found is always non-uniformly distributed, cases where it maximum larger by factor approximately ten values calculated plane slab or average cross section model.
