Dielectric Behaviour of Human Blood at Microwave Frequencies

Abstract

IN the course of studies of microwave absorption in human tissues, measurements have been made of the dielectric constant, ε′–jε″, of whole human blood at a number of frequencies in the range 1.78 × 109 c./s. to 2.36 × 1010 c./s., employing coaxial-line and wave-guide methods described elsewhere1,2. The specimens used had red cell concentrations within the limits 4.9 ± 0.1 × 106 cells per mm.3 and were heparinized to prevent coagulation.
