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.
