Abstract: Metal hybrid waveguide couplers, which are crucial passive structures in terahertz (THz) in-phase-quadrature (IQ) mixers, have raised significant attention in the development of high-speed ...

Abstract: This article presents a dual-band rat-race coupler for high band ratio wireless applications. In this article, a dual-band transmission line (TL) has also been proposed to design the ...

NearFi plug-and-play contactless couplers for industrial applications enable the real-time transmission of power and Ethernet data across air gaps of a few centimeters, providing critical convenience, ...
