摘要
We study the scattering of electromagnetic waves by mushroom-type metamaterials such that the metallic wire array and the patch grids have different symmetry centers. Based on a quasi-static model, we develop an analytical formalism to compute the reflection and transmission characteristics of a metamaterial slab, and derive suitable boundary conditions for the patch grid interfaces. The theory is successfully compared with full-wave simulations.
