Broadband Reflectionless Metasheets: Frequency-Selective Transmission and Perfect Absorption
Energy of propagating electromagnetic waves can be fully absorbed in a thin lossy layer, but only in a narrow frequency band, as follows from the causality principle. On the other hand, it appears that there are no fundamental limitations on broadband matching of thin resonant absorbing layers. Howe...
