Abstract

In this paper complex materials like stratified resins were studied. The resins where simulated using a high level computing program: High Frequency Structure Simulator (Ansoft Technologies), in order to determine their behavior at high frequencies, specific for the microwave fields. This task is imposed by the necessity of stratified materials usage at high frequencies and at higher temperatures. Simulation results, punctually confirmed by the experiments, are the basis for developing a new formula for the effective permittivity of the stratified materials, which indicates the dependence of this quantity of the geometrical and physical parameters of the samples and also indicates its frequency dependence. Conclusions are available, consecrated to the work strategy for mixed structures simulations in microwave field and to the strategy of formula synthesizing for material properties determination in this frequency range..
