Abstract: “n this study a novel non-planar dual split ring resonator (DSRR) has been proposed to achieve high sensitivity and produce variable resonant frequencies and quality factors. This has been achieved by varying distance between two conventional split ring resonators (SRRs). Four different materials i.e. glass, mica, rubber and plastic are used for the analysis of SRR and DSRR. Effects on quality factor and resonant frequency of the two structures through HFSS software has been studied. Due to the insertion of materials in gap of resonator, electric field is perturbed. Perturbation results change in resonant frequency and quality factor of resonator. It was observed that different material resulted shifts in resonant frequency and quality factor in different manner due to unique material permittivity. Hence different sets of shifts in resonant properties were obtained. Results of both conventional and proposed design are presented and compared.”
