Recent research published in Coatings suggests a brand-new, high-performance metamaterial absorber with ultra-broadband high polarization selectivity and absorption throughout the LWIR atmospheric window. The absorber can achieve an absorptance of 90% with a 4700 nm bandwidth owing to various surface plasmons combined with optical phonons.
