Prototype sub-wavelength structure anti-reflection coating on alumina filters for ground-based CMB telescopes
Kosuke Aizawa, Ryosuke Akizawa, Scott Cray +8
We present designs and fabrication of sub-wavelength anti-reflection (AR) structures on alumina for infrared absorptive filters with passbands near 30, 125, and 250 GHz. These band…
