Waveguide Model for Thick Complementary Split Ring Resonators

This paper presents a very simple analytical model for the design of Frequency Selective Surfaces based on Complementary Split Ring Resonators (CSRR) within the microwave range. Simple expressions are provided for the most important geometrical parameters of the model, yielding an accurate description of the CSRR resonance frequency and avoiding full-wave numerical simulations. Besides, a qualitative description of the band-pass filter behavior of these structures is described, considering its high quality factor Q.Comment: Paper accepted at the 2014 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting. paper submission #286
