零电磁材料特性模拟及分析
Simulation and analysis of zero-electric and zero-magnetic materials
摘要
Abstract
Waveform converting and angular filtering properties of zero-electric and zero-magnetic(ZEM) materials slab were simulated under line source,TM wave and dipole irradiation,respectively,using finite-difference time-domain(FDTD) method.Simulation results show that electromagnetic wave can tunnel through the ZEM materials when the wave impinges on the entrance face of the materials perpendicularly;the phase pattern of the transmitted wave is dependent on the exit faces of ZEM materials;when the electromagnetic waves emitted from a line source or dipole transmit through a ZEM materials slab with planar exit face,it can be transformed into perfect plane waves.Moreover,the ZEM materials can be used in the design of antenna array.The radiation intensity of the ZEM material-assisted antenna array which has N elements is increased to N0.5 times.关键词
