Abstract
Circuit model analysis extensively used to describe metamaterials response at radio and microwave frequencies needs significant revision for application to metallic resonators in the infrared frequency range. A self consistent filament current based approach is elaborated providing parameter values accurately describing resonators internal properties as well as inter-resonator couplings. The model is verified by comparing the excitations in a five element array obtained from the numerical simulation using CST MWS solver with the predictions provided by the model. Although the results presented here concern with loop like magnetic resonators, the model can also be extended to other resonator shapes, for example metallic rods.
