Perfect subwavelength fishnetlike metamaterial-based film terahertz absorbers
Abstract
We present two different designs of robust, easily manufactured metamaterial-based films of subwavelength thickness capable of full absorption of incident terahertz radiation at certain frequencies. Both designs allow a choice between the total absorption of all polarizations or only one linear polarization while the other polarization is reflected. Even if the films are optimized for normal incidence, the absorption remains greater than 99% for angles up to $\ensuremath{\sim}35\ifmmode^\circ\else\textdegree\fi{}$ in the TE and up to $\ensuremath{\sim}65\ifmmode^\circ\else\textdegree\fi{}$ in the TM case. In the first design, the maximum absorption frequency shifts considerably with angle, and in the second design it is independent of angle.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
