Single port bio-sensor design using metamaterial split ring resonator

Metamaterial are artificially made electromagnetic materials consisting of periodically arranged metallic elements which are less than wavelength of incident wave in size. They can exhibit a strong localization and enhancement of fields, which may provide a tool to significantly enhance the sensitivity and resolution of sensors. Slotted Ring Resonator (SRR) is one type of such metamaterial. In this paper we will present the design of a single port double SRR concentric rings. The concept of structure resonance will be applied to the design of the sensor to be used in bio-sensor application. The design is verified using High frequency simulation software HFSS, and different five different biological material samples are tested and placed in the SRR gab. It was observed that a shift in the resonance frequency takes place as different materials are place in the SRR gab.
