High-efficiency and ultrabroadband flexible absorbers based on transversely symmetrical multi-layer structures

Two ultrabroadband and omnidirectional perfect absorbers based on transversely symmetrical multilayer structures are presented, which are achieved by four absorptive metal chromium (Cr) layers, antireflection coatings, and the substrates, glass and PMMA, in the middle. At the initial step, the propo...
