STUDY OF BIO-EFFECTS OF MILLIMETER WAVE PROPAGATION ON TISSUE

This paper highlights the effect of millimeter wave (MMW) radiation on biological tissue for prolonged exposure to record thermal effects. The novel method described in this article is simulation of exposure of millimeter waves on tissues and study the thermal effects resulting from radiation. To simulate this, a setup to uniformly irradiate a tissue of about 2.2 mm thickness is described, and 3D visualization of MMW propagation is modeled using COMSOL Multiphysics radio frequency module at frequencies around 30 GHz. Heat generation and consequent temperature rise in the three-layer tissue structure is followed by analysis of temperature variation due to radiation absorption.
