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…
Design of ALPHA Phase I: A Plasma Haloscope for 10--20 GHz Post-Inflation Axions
ALPHA Collaboration, Xiran Bai, Rustam Balafendiev +53
The axion is a well-motivated hypothetical particle capable of resolving both the strong CP problem and the dark matter mystery, with recent post-inflationary cosmological simulati…
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…
The Simons Observatory: forecasted constraints on primordial gravitational waves with the expanded array of Small Aperture Telescopes
The Simons Observatory Collaboration, I. Abril-Cabezas, S. Adachi +479
We present updated forecasts for the scientific performance of the degree-scale (0.5 deg FWHM at 93 GHz), deep-field survey to be conducted by the Simons Observatory (SO). By 2027,…
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,…
Spiral Tuning of Wire-metamaterial Cavity for Plasma Haloscope
Jacob Lindahl, Rustam Balafendiev, Gagandeep Kaur +5
Axions are hypothetical particles that provide a compelling solution to two major mysteries in modern physics: the strong CP problem and the nature of dark matter. The plasma halos…
Tunable Epsilon Near Zero Metamaterial with Rotating Obround-Shaped Meta-Atoms
Rustam Balafendiev, Gagandeep Kaur, Jim A. Enriquez +4
A new design of a microwave-range ENZ metamaterial consisting of rods with an obround cross-section is proposed. The plasma frequency of the metamaterial can be tuned by rotating t…
Uniform Field in Microwave Cavities Through the Use of Effective Magnetic Walls
Jim A. Enriquez, Rustam Balafendiev, Alexander J. Millar +2
Wire media (WM) resonators have emerged as promising realization for plasma haloscopes -- devices designed to detect axions, a potential component of dark matter. Key factors influ…
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…
Searching For Dark Matter with Plasma Haloscopes
Alexander J. Millar, Steven M. Anlage, Rustam Balafendiev +24
We summarise the recent progress of the Axion Longitudinal Plasma HAloscope (ALPHA) Consortium, a new experimental collaboration to build a plasma haloscope to search for axions an…
Wire metamaterial filled metallic resonators
Rustam Balafendiev, Constantin Simovski, Alexander J. Millar +1
In this work we study electromagnetic properties of a resonator recently suggested for the search of axions - a hypothetical candidate to explain dark matter. A wire medium loaded…
