The company’s Web site, www.heli-cal.com/cm/products/flexible-couplings/home.html, lets users view and download 3D CAD models of standard curved-beam flexible-shaft ...

Efficient grating couplers (GCs) for perfectly vertical coupling are difficult to realize due to the second-order back reflection. In this study, apodized GCs (AGCs) are presented for achieving ...

Quadrature (90-degree) hybrid couplers play an important role in various RF system like receivers, transmitters, signal analysis/processing circuits etc., for phase shifting, power combining, and ...

This paper introduces a novel broadband 3-dB coupler based on ridge gap waveguide (RGW) technology designed using supershapes to achieve exceptional bandwidth while maintaining a compact footprint. By ...
