Abstract
An open‐ended coaxial line sensor in conjunction with an automatic network analyzer was used to measure in vivo the permittivity of several feline tissues (skeletal and smooth muscle, liver, kidney, spleen, and brain – gray and white matter) at frequencies between 10 MHz and 1 GHz. The estimated uncertainties of measurement were between 1.5% and 5%. The data are in general agreement with previously obtained data in vitro and in vivo. Significant differences in the properties of different types of the same tissue (eg, skeletal and smooth muscle) were observed. Many tissues were found to be non‐homogeneous in its permittivity.

Dielectric measurements were performed on concentrated suspensions of TiO 2 (50 vol%) and clay (40 vol%) in the frequency range 1 MHz-1 GHz. The suspension rheology was modified by various Tiron or sodium tripolyphosphate additions. Using a specific procedure for data interpretation, it was shown th
The reason for using acupuncture points as exposure sites in some applications of millimeter wave therapy has been unclear. Acupuncture points have been suspected to exhibit particular direct current (DC), low-frequency electrical and optical properties compared to surrounding skin. To assess if suc
