Ultra-narrow-band terahertz perfect metamaterial absorber for refractive index sensing application

Ultra-narrow-band terahertz perfect metamaterial absorber for refractive index sensing application

We numerically propose and demonstrate an ultra-narrow perfect metamaterial absorber (PMA) for refractive index sensing applications in the terahertz region. The designed PMA is only composed of a gallium arsenide (GaAs) cross-shaped resonator array on an opaque copper/silicon substrate. Simulated r...
