Effective Medium Model for Multilayered Anisotropic Media with Different Orientations
Keywords:
Effective medium theory, multilayered anisotropic media, parameter extractionAbstract
An efficient model is developed to simulate multilayered biaxial anisotropic material with different orientations by using effective medium theory. Equivalent model is used to extract effective permittivity, permeability and orientation angle for multilayered biaxial anisotropic medium. Analytical expressions for effective parameters and orientation angle are derived for low frequency (LF) limit. The model also gives a non-magnetic effective anisotropic layer if each layer is non-magnetic anisotropic dielectric. Good agreement is achieved by comparing the effective parameters extracted with and without low frequency approximation. We show that the frequency-independent equivalent model is valid for frequency up to 10 GHz.
