Abstract

Two new open-ended coaxial sensors for in-vivo Measurements of the dielectric properties of biological tissues at low radio frequencies are described. The high fringing-field capacitance of these sensors allow accurate measurements of high-water-content tissues at frequencies as low as 10 kHz. Each sensor is represented by two capacitances (C0and Cf) which are calculated using the method of moments. Theoretical and experimental results for experimental sensors terminating a standard I4-mm coaxial line with a GR900 connector are presented.
