Abstract
Application of thin metal absorbers allows one to significantly increase the absorption coefficient and sensitivity of matrix THz microbolometric detectors. It is shown that absorbers characterized by frequency dispersion of conductivity, in contrast to conventional nondispersive absorbers, can provide almost total IR absorption retaining high sensitivity in the THz range.
