Design and Analysis of a Meta Material based Nested Circular Split Ring Resonator for Terahertz Applications

In this paper nested circular split ring resonator structure is implemented using metamaterials at terahertz frequency range. The mathematical analysis of a resonator structure is made to estimate the resonating frequency. Transmission characteristics of a resonating structure are extracted using CST software to demonstrate the behaviour of metamaterials at tera hertz frequency. This paper comprises the investigation of a nested circular split ring resonator frequency response ,that is by increasing the no of circles .The simulation results shows that by increasing the no of circles, no of resonating frequencies also increases that is at 1.2THz ,2.1THz and 2.42 THz which is used as a multiband antenna and also we can observe the absorbivity at terahertz frequency regime which is used for imaging and sensing applications .
