Reststrahlen band optics for the advancement of far-infrared optical architecture
… single parameter was shown to provide absorption resonance tuning across a wide range of the far-infrared with marginal change in the strength and quality factor of the resonance. Subsequent heating of the devices with 2D gratings demonstrated polarization independent selective thermal emission. …
