Electromagnetic Parameter Retrieval Method Based on Floqeut Mode Analysis
基于Floquet模式的异向介质参数提取方法

A rigorous analysis of Split Rring Resonator (SRR) metamaterials is presented for three different electromagnetic field polarization and propagation directions to establish the SRR resonance behaviors. The Smith’s parameter retrieval method is then extended to Floquet mode analysis, and the S parameters from the two methods are compared. The resonances of SRR with different orientation is investigated to testify the proposed analysis. Compared with traditional methods, parameter retrieval method based on Floquet mode analysis reduces greatly the time to calculate the S parameters, thus it is more convenient for the analysis of metamaterial bianisotopic effects.
