A fast and efficient permittivity estimation method for artificially engineered microwave materials

A simulation based method is proposed to estimate the effective permittivity of artificially engineered materials with controlled electromagnetic properties, that can increase the effective permittivity of low permittivity dielectrics. Details of the proposed method and the results for a sample with window-shaped inclusions are discussed. The method provides a systematic approach to study the influence of different parameters on the effective permittivity, which is necessary for using these materials in antenna design.
