Resonant Characteristics of Split Ring Resonator and Unit Cell for Periodic Metamaterial Devices

摘要

The resonant characteristics of single split ringresonator-based metamaterial devices with single gap arepresented using the analytical formulation developed for thelumped element equivalent circuit model. The characteristics ofthe metamaterial resonators have been investigated for differentring sizes, gap widths and substrate permittivity. Equivalentcircuit model is developed for two ring structures. The analytical,and simulation results are compared and verified. The prototypehas been then built and measured. It has been observed that allthe results agree. The results presented in this paper can be usedto develop devices at the THz range that can operate as sensors,antennas or tuning elements.
