Sažetak
Today, biological tissues are exposed to electric fields in order to induce certain biological effect - for instance, the electropermeabilization of cell membranes. The exposure is, however, often unintentional coming from numberless electrical devices and appliances. In this contribution we present basic methodology for modeling and understanding the electrical response of biological tissue to harmonic and pulsed electric fields of various intensities and frequencies. The focus is on short-term electrical and thermal response of tissue. The methodology is based on basic concepts of electromagnetic theory. Biological tissue is characterized, as any other material, with its macroscopic (bulk) physical properties (electrical conductivity, permittivity, etc.). However, the calculation of the electric field and the current density in tissue is difficult because macroscopic tissue properties show inhomogenity, dispersions, anisotropy, nonlinearity, as well as temperature dependence and changes over time.
