Broadband, millimeter-wave antireflection coatings for large-format, cryogenic aluminum oxide optics

A. Nadolski, J. D. Vieira, J. A. Sobrin +86

We present two prescriptions for broadband (~77 - 252 GHz), millimeter-wave antireflection coatings for cryogenic, sintered polycrystalline aluminum oxide optics: one for large-for…
