Transmission Properties of Grating Structures Containing Lossy Negative Permittivity Material
We studied the transmission properties of a new grating structures composite of the matching heterostructure units containing lossy negative epsilon materials and photonic crystals by using finite element analysis. The transmittance was analyzed by comparing various grating period length and the different ratio of heterostructure in grating structures
respectively. The above results show that the transmittance of grating structures dramatically increases compare with the single heterostructure. Simultaneously
we expound the physical reason of the enhanced transmittance from the distribution of electromagnetic fields. That is because of the periodic modulation for electromagnetic fields in the new gating structures.
