Measurement of complex dielectric permittivity of organosilicon compounds in the microwave range for application as insulation in nonlinear transmission lines with ferrite

Abstract

The complex dielectric permittivity of silicon compounds is measured in the microwave range. The measurement is carried out using a method based on determining half-wave resonances in a coaxial line filled with a dielectric with unknown properties. Based on the measurements obtained, the excitation of high-frequency oscillations in a nonlinear transmission line with saturated ferrite with high-voltage insulation in the form of a silicon compound is simulated numerically. The complex permittivity dependence on frequency is described by the Lorentz model.
