Abstract

Microwave technology has provided with many exciting new therapeutic and diagnostic methods. Frequencies from RF as low as 400 kHz through microwave frequencies as high as 10 GHz are presently used for therapeutic applications in areas such as cardiology, urology, surgery, ophthalmology, cancer therapy and for diagnostic applications in areas such as cancer detection, organ imaging and more. At the same time, microwaves affect living systems directly at a low level of exposure. The effects of microwave interaction with living system are the result of the penetration of the EM waves into the living system, propagation into it and interaction with biological tissues. This paper shows penetration depth of EM wave in different parts of body and electric field, temperature and Specific Absorption Rate (SAR) caused by EM wave in human body as well as human brain. It also shows spherical 6-layer model of head, 1-layer and 3-layer geometry of low profile antennas implanted in human chest.
