摘要

Based on analytical derivations and numerical simulations, we show that both reflection and transmission can be canceled at the surface of a metamaterial (MM) with a metal–dielectric stratified structure. Strong anisotropic absorption and the surface direction are found to play important roles in this phenomenon. For the angle between the surface and the layers of MMs above a critical value, only reflection is eliminated and transmission is permitted. Since they are not related to resonance, the phenomena can occur in a broad frequency range.
