Research output: Contribution to journalConference articlepeer-review


We inversely design a sub-vacuum-wavelength thick metamaterial comprising meta-surface, microcavity, and ultra-thin photo-absorber, with an absorptance spectrum ∼ 99% peaked at 3.5µm, maintaining this level over a flattop range around this wavelength.
