Characteristic analysis of different periodic arrangement ways of low-frequency metamaterial structure

S parameters of three periodic arrangement ways of low-frequency metamaterials structure were simulated by HFSS software based on square dual-layer planar spiral structure model, including periodic tiling arrangement structure, periodic parallel arrangement structure and periodic cross arrangement structure. Effective electromagnetic parameters were extracted from the S parameters to analyze metamaterial characteristic of the three arrangement ways in low-frequency range. The simulation results show that the incident wave can be completely reflected back by the periodic tiling arrangement structure, the periodic parallel arrangement structure is a kind of low-frequency magnetic negative metamaterial and the periodic cross arrangement structure is a kind of low-frequency left-handed material.
