We propose to develop broad-band metamaterial antireflection (AR) coatings for the far-infrared and millimeter wave bands. The proposed coating technology could realize an unprecedented combination of low reflectance, negligible dielectric loss, and broad bandwidth for large diameter cryogenic refractive optics. The projected performance of the proposed technology matches the desired attributes for optical coatings intended for astrophysical instrumentation.
The effort's objective is to realize broadband low-reflectance coatings. The two key technical challenges are the design of the precision engineered materials and their characterization.More »
Broadband meta-material coatings are applicable in the millimeter and sub-millimeter for astrophysical instrumentation (e.g., CMBpol, SOFIA, SPIDER) and remote sensing. This technology also enables compact THz imagers for concealed threat detection and spectrometers for explosives detection.More »
