Abstract

The ability of metamaterials to concentrate energy of the incident radiation on the sub-wavelength scale has long been predicted to lead to new device applications with a significantly improved and even superior functionality; the concrete implementations are, however, only beginning to emerge. Here we show how combining the concept of a superconducting bolometer with the coherent metamaterial paradigm allows to create a very sensitive sub-THz radiation detector with high spectral selectivity of ν₀/Δν ~ 90.
