Design and analysis of bandpass waveguide filters using novel complementary split ring resonators

This paper presents models of the bandpass waveguide filters using novel complementary split ring resonators. These resonators are employed as single-mode and dual-mode. Dual-mode resonators are developed from the single-mode ones. The filter response is analyzed in terms of various parameters of the resonators. The possibility to independently tune single-mode resonators, contained in the dual-mode resonator, is also investigated, in order to evaluate this solution for modeling of the resonators with multiple resonant frequencies.
