Pushing the Limits of Broadband and High Frequency Metamaterial Silicon Antireflection Coatings
K. P. Coughlin, J. J. McMahon, K. T. Crowley +4
Broadband refractive optics realized from high index materials provide compelling design solutions for the next generation of observatories for the Cosmic Microwave Background (CMB…
Composite Reflective/Absorptive IR-Blocking Filters Embedded in Metamaterial Antireflection Coated Silicon
C. D. Munson, S. K. Choi, K. P. Coughlin +4
Infrared (IR) blocking filters are crucial for controlling the radiative loading on cryogenic systems and for optimizing the sensitivity of bolometric detectors in the far-IR. We p…
Deep Reactive Ion Etched Anti-Reflection Coatings for Sub-millimeter Silicon Optics
Patricio A. Gallardo, Brian J. Koopman, Nicholas Cothard +8
Refractive optical elements are widely used in millimeter and sub-millimeter astronomical telescopes. High resistivity silicon is an excellent material for dielectric lenses given…
A Broadband Micro-machined Far-Infrared Absorber
Edward J. Wollack, Aaron M. Datesman, Christine A. Jhabvala +2
The experimental investigation of a broadband far-infrared meta-material absorber is described. The observed absorptance is from () ov…
