Introduction:: Surface-emitting terahertz quantum cascade lasers (THz QCLs) are highly promising for applications requiring high-quality far-field beams and controlled beam divergence. However, ...

Augmented reality (AR) technology developer Magic Leap has signed an agreement with the Taiwan-based electronics manufacturer ...

For the system noise temperature calibration of the K/Q/W triple-band cryogenic receiver on Tianma Radio Telescope (TMRT), a design of W-band eight-hole waveguide directional coupler is proposed in ...

Frequency combs are becoming one of the great enabling technologies of the 21st century. High-precision atomic clocks, and high-precision spectroscopy are just two technologies that have benefited ...

Abstract: This paper presents the design of an all-metal antenna based on Gap Waveguide technology. The antenna, which is realized using a Ridge Gap Waveguide, consists of just two layers, maintaining ...

Abstract: This article describes a practical method to design waveguide tapers with smooth profile. A tapered waveguide, in general, is used to match different waveguide sections with the lowest ...

Pilots flying the Embraer Legacy 450 and 500 business jets are among the first to be using an augmented reality-based technology within their head-up displays (HUDs). The technology, waveguide optics, ...

The drive to shrink advanced electro-optical medical instrumentation on-chip and in-chip continues along diverse paths. For example, optical coherence tomography (OCT) is a relatively new but now ...
