Multi-mode coupled focal planes for high precision measurements of large scale CMB polarization

Description

We describe the design and properties of a multi-mode detector system for photon detection at mm wavelengths. We modeled its basic elements (absorber, integrating cavity, waveguide and horn antenna) through numerical simulations, and built a prototype single-pixel system for performance validation. Following a successful verification of the modeling approach, we plan to optimize the system performance in view of applications to CMB polarization measurements with large throughput focal planes. © 2013 IEEE.
