Accurate Determination of the Complex Permittivity of Biological Tissue Around 35 GHz
Abstract
Apparatus is described which enables the complex permittivity of liquids and solid tissue to be measured at a frequency of 35 GHz. The results are presented on various rabbit tissues, including muscle, fat, skin, brain tissues, and eye lens; and some phantom tissue equivalent materials have been devised. Various liquids have been measured, including rabbit blood, water, and saline. The results have been examined for any evidence of an anomalous/resonant behavior, but none was found. Keywords: Microwave, Dielectric properties, Waveguide circuits, Computer programs, Experimental data, Air Force research.
