Abstract

Frequency and temperature dependence of the dielectric parameters like dielectric constant (ε') dielectric loss (ε"), conductivity (σ) loss tangent (δ), and capacitance (F), of biological tissues have been studied. fish catla catla (cytrinidae) which were scales tissues sample, of thicknesses .75mm and diameter 4X4mm, are studied in the frequency range (1Hz-10MHz and in the temperature range (30-150℃). There frequency and temperature dependence study have been quantitatively explained. The magnitude of dielectric loss decreases with increasing frequency. The temperature dependence of dielectric constant increases rapidly with temperature particularly in temperature region where dielectric loss peak occurs. It is not clear fish scales can used to any advantage. However, the high dielectric constants of these scales at low frequencies (around 1KHz) suggest that they could in, in principle, be used for capacitor applications. Further theoretical and experimental investigations will be carried out to frequency dependence of complex permittivity of biological tissues.
