Effective Permittivity Calculation of Composites with Interpenetrating Phases

摘要

The effective permittivity of composites with interpenetrating phases was determined through finite-element simulation. The spectra of effective permittivity for such composites were calculated, and relationships among the effective permittivity ε _eff, permittivity ratio x of the matrix to network phase, and volume fraction of the network f were developed using the numerical results. The simulation has been validated by comparing the results with previously published experiments, and excellent agreement has been achieved. The electric field distributions in the composites were also explored in this work.
