Coupled Line Approach for a Split Ring Resonator Modeling

摘要

A novel circuit model for the SRRs using coupled lines is proposed which is capable for accurate microwave resonator application design. The even and odd modes characteristic impedances and effective permittivities of the coupled line and the gaps of the SRR are obtained by the full-wave FEM simulations. The simulated resonant characteristics for the SRR prototypes agree well with corresponding measured results and validity of the proposed model is confirmed.
