Abstract
En 中文
Calculation of the Fresnel coefficients and conservation of power equations at the interface between two mediums require modifications when the mediums are complex. The Fresnel equations and new conservation equations were derived for both transverse electric and transverse magnetic polarizations that account for complex permittivity and complex permeability. The derived equations work for any combination of signs for the real and imaginary parts of permittivity and permeability to accurately handle active and passive mediums, positive and negative refractive indices, and positive and negative impedances. The results are verified, and a comprehensive set of benchmarking examples is provided for different combinations of complex constitutive parameters. Consideration of general complex constitutive parameters in the formulation is important for metrology and simulating metamaterials because it has not been considered anywhere in the literature.
