Abstract
Waveguides systems have been used to obtain measurements for the complex permittivity of human blood in the frequent range 29-90 GHz. The data are reported and analysed in conjunction with lower frequency work, in particular that of Wei. There are two distinct regimes of behaviour in the spectra obtained: a high-frequency relaxation process in parallel with a lower frequency fractional power-law response.Keywords
