Abstract

In this letter we investigate an artificially synthesized absorbing medium by using the finite-difference timedomain (FDTD) and waveguide simulation techniques. The artificial medium comprises a doubly periodic array of lossy electrical and magnetic media (i.e., an ε-only and μ-only checkerboard) and we compute its reflection coefficient for normal and oblique angles of incidence. It is demonstrated that, if properly designed, the reflection characteristics of the checkerboard are far superior to those of a uniform material of the same thickness with ε=μ.
