Electric field distribution in biological systems [PDF]

open access: yesJournal of Biological Physics, 1974
Electric field distribution in biological systems was investigated. In the analysis both the conductive and the dielectric properties of biological systems were considered. Making use of the complex dielectric coefficient, equations which describe the electric field behavior in such media, were formulated.
