Sažetak
Either to induce certain biological response, or without that intention, in different situations biological tissues are exposed to static or dynamic electric fields of various intensities. The purpose of this paper is to point out to the important issues when modeling the electric field in tissues and when measuring the electrical properties of tissues. Our approach here is to treat the tissue as a material described by its macroscopic (bulk) properties to which we apply the classical theory of electromagnetic fields. Therefore, we briefly reviewed the fundamentals of electromagnetic theory, we introduced properties of materials and explained terms such as inhomogeneous, anisotropic, dispersive and nonlinear. We illustrated the introduced concepts on the electrical conductivity and permittivity of biological tissues. We discussed the equivalence of response in frequency and time domain and the necessary assumptions. Then we presented the results of measuring tissue properties that involve nonlinear ef-fects. Finally, we summarized the most important factors affecting electrical properties of tissues, as well as factors affecting the accuracy of measurement methods.
