Antenna-coupled Tunnel Diodes For Dual-band Millimeter-wave/infrared F
The infrared and millimeter-wave portions of the spectrum both have their advantages for development of imaging systems. Because of the difference in wavelengths, infrared imagers offer inherently high resolution, while millimeter-wave systems have better penetration through atmospheric aerosols …

Antenna-coupled Infrared And Millimeter-wave Detectors: Fabrication, Measurement And Optimization
Antenna-coupled detectors provide uncooled, cost-effective solutions for infrared and millimeter-wave imaging. This work describes the design, fabrication, measurement, and optimization of several types of antenna-coupled detectors for LWIR (8 - 12 µm) and 94 GHz radiation. Two types of …

Superdirectivity and the Application of Complementary Split Ring Resonators in Directivity Enhancement of Millimeter-Wave Antennas
The use of millimeter wave frequencies is extending to a variety of applications with the development of 5G/6G networks. Due to the small physical size in addition to atmospheric absorption and material losses, millimeter wave antennas suffer from low radiation performance. Motivated by this …
