THE EFFECTIVE CONSTITUTIVE PARAMETERS AT INTERFACE OF DIFFERENT MEDIA

By L. G. Zheng and W.-X. Zhang

Full Article PDF (127 KB)

Abstract:
This paper presents a new approach to estimate effective constitutive parameters for a cell across an interface between two bianisotropic media. The work is different from those studying effective properties of bi-anisotropic mixtures in that the boundary conditions of field components are taken into consideration. The degenerated cases, including interfaces of two bi-isotropic, anisotropic and isotropic media, are discussed respectively in detail. Simulation for anisotropic media shows significant improvements can be expected from the adoption of the new approach.
