Abstract
We numerically investigate the influence of curved surface on the properties of metamaterial absorber in the microwave regime. It is shown that curved surface metamaterial absorber can lead to dramatic absorption increase compared with the conventional planar structure. Simulation results demonstrate that the proposed absorber can perform absorption peaks at two resonant frequencies and one resonant frequency for the TM and TE polarizations, respectively. This simple absorber is particularly desirable for various potential applications such as improving absorbance performances.
