TL;DR: The Bicep/Keck Array (BK) program targets the degree angular scales, where the power from primordial B-mode polarization is expected to peak, with ever increasing sensitivity and has published the most stringent constraints on inflation to date as discussed by the authors.
Journal ArticleDOI
A Compact Machinable 90° Waveguide Twist for Broadband Applications
TL;DR: In this article, a machinable 90° waveguide twist design for broadband applications from microwave to terahertz frequency was presented, which achieved a performance of −25 dB return loss for full waveguide bandwidth.
Journal Article
An SIS mixer based focal-plane array at 230 GHz
TL;DR: In this paper, a 1×4 FPN array unit based on finline SIS mixers, fed with smooth-walled feed horns, is described, which is achieved by a combination of vertically machined waveguide Y-power splitters and bow-tie cross-collaborative couplers.
Journal ArticleDOI
A Silicon Chip-Based Waveguide Directional Coupler for Terahertz Applications
Lingzhen Zeng,Wei-Chun Lu,P. Grimes,Tse-Jun Chen,Yen-Pin Chang,Cheuk-yu Edward Tong,Ming-Jye Wang +6 more
TL;DR: In this article, a waveguide directional coupler design with weak coupling using silicon-based suspended coupling microstrip probes and the split-block type of construction common in integrated millimeter wave components was proposed.
