Nonreciprocal Perfect Absorber Consisting of Nonlinear Plasma and Matching Metamaterials

摘要：

　　A novel,compact and multichannel nonreciprocal absorber through a wave tunneling mechanism in epsilon-negative and matching metamaterials is theoretically proposed.Non-reciprocal absorption properties are acquired via the coupling together of evanescent and propagation waves in an asymmetric configuration,constituted of nonlinear plasma alternated with matching metamaterial.The absorption channel number can be adjusted by changing the periodic number.Due to the positive feedback between nonlinear permittivity of plasma and the inner electric field,bistable absorption and reflection are achieved.Moreover,compared with some designs proposed before,our design is more compact and independent of incident angle or polarization.This kind of multilayer structure offers additional opportunities to design novel ormidirectional EM wave absorbers.
