Kavli Affiliate: Tomotake Matsumura | First 5 Authors: Kosuke Aizawa, Ryosuke Akizawa, Scott Cray, Shaul Hanany, Shotaro Kawano | Summary: 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 bands are widely used by ground-based instruments measuring the cosmic […]
