Effect of Substrate Etching on Terahertz Metamaterial Resonances and Its Liquid Sensing Applications
We investigate the effect of substrate etching on terahertz frequency range metamaterials using finite-element method simulations. A blue shift was found in the metamaterial resonance with increasing substrate etch depth, caused by a decrease in the effective refractive index. The relative contribut...
