Effects of manufacturing tolerances on the performance of metamaterial microwave anti-reflection coatings
Rustam Balafendiev, Miranda Eiben, Jon E. Gudmundsson
Metamaterial anti-reflection coatings (ARC) are used in a variety of applications, including: lenses, filters, and absorbers. Typically, the design of a given ARC is done within an…
Millimeter and sub-millimeter characterization of polymers used for infrared filters in high-sensitivity cryogenic microwave telescopes
Miranda Eiben, Rustam Balafendiev, Thomas Gascard +1
Vacuum windows and infrared filters are important transmissive optical components in millimeter receivers, as they hold out the atmosphere and reduce radiative loading on cold stag…
Polarization rotation through differential transmission in refractive CMB telescopes identified using a hybrid physical optics method
Xiaodong Ren, Rustam Balafendiev, Jon E. Gudmundsson
We identify a polarization rotation systematic in the far field beams of refractive cosmic microwave background (CMB) telescopes caused by differential transmission in anti-reflect…
Optimizing broadband microwave absorbers for applications in the 70-200 GHz range
Gaganpreet Singh, Rustam Balafendiev, Mahesh Singh Bist +4
We present results of an extensive suite of numerical simulations that probe square-tiled microwave absorber performance as a function of material properties, frequency, geometry,…
Vector beam mapping at millimeter wavelengths using a robot arm
Rustam Balafendiev, Thomas Gascard, Jon E. Gudmundsson
Many experimental efforts are striving to provide deep maps of the cosmic microwave background (CMB) to shed light on key questions in modern cosmology. The primary science goal fo…
Reflectance measurements of mm-wave absorbers using frequency-domain continuous wave THz spectroscopy
Gaganpreet Singh, Rustam Balafendiev, Zeshen Bao +4
Due to high dynamic range and ease of use, continuous wave terahertz spectroscopy is an increasingly popular method for optical characterization of components used in cosmic microw…
