Abstract :
A new fringing-field capacitor for in-vivo studies of biological tissues at low radio frequencies is proposed. It consists of multiple coaxial rings fed with alternating polarity and allows an increase in the fringing-field capacitance by an order of magnitude, as compared with a standard open-ended coaxial line. The parameters of the equivalent circuit are found using the moment method. Theoretical and experimental results for test capacitors terminating a standard 14-mm coaxial line with a GR900 connector are presented.
