Equivalent Electromagnetic Currents on Infinite Stratified Homogeneous Bi-anisotropic Media Backed by A PEC Layer摘要
In this work, the equivalent electromagnetic (EM) currents on the surface of stratified homogeneous bi-anisotropic media backed by a perfect electric conductor (PEC) layer are derived and investigated. By using the representation of Maxwell's equations with a first-order state-vector differential equation, the tangential field components and the corresponding equivalent EM currents at the interface between the outmost bi-anisotropic media layer and the free space is derived analytically and can be easily degenerated into the single anisotropic and isotropic cases. This work is considered as a further step in the study of the EM characteristics of stratified complex media and the obtained results may provide a way for approximately fast calculation of the EM scattering from PEC targets coated by stratified homogeneous bi-anisotropic media. Simulation results are given to validate our analysis and conclusions.
