Narrowband diffuse thermal emitter based on surface phonon polaritons

Thermal emission engineering with ability to realize spectral and spatial selection has attracted great attention in recent years. Nanophotonic control of thermal radiation has demonstrated narrowband thermal emitter but with high angle-sensitivity and diffuse thermal emitter but with low quality factor (Q). Here, we demonstrate a simultaneous narrowband, diffuse thermal emitter consisting of 80 nm (

Automated summary

Thermal emission engineering with spectral and spatial selection capability has gained attention, and a new narrowband, diffuse thermal emitter has been successfully demonstrated to address the issues of high angle-sensitivity and low quality factor in thermal radiation control.
