Solar absorbers are designed for absorbing visible, infrared, and ultraviolet frequencies.
Most of the absorbers designed so far have been for absorbing visible frequencies, and …

A bow-tie antenna with a step-edge Josephson junction as the detection element, located at
the center of the antenna, was investigated. The performance of these detection systems is …

We propose a broadband end-fire antenna for continuous-wave terahertz (THz) photomixing–
based devices working in the frequency range of 0.5–1 THz. A compact Vivaldi antenna is …

Multichannel very high frequency (VHF) high-power transmission system, based on a 90°,
high-temperature superconductor YBa 2 Cu 3 O 7 (YBCO) hybrid coupler is presented. The …

A high-performance S-band down-conversion microstrip mixer, for operation from 77 K to
300 K, is described. The balanced mixer combines a 90 degree hybrid coupler, two Schottky …
