Waveguide has many practical uses in high-powered RF systems, as covered in the last tutorial. Specifically, it is used as a transmission line for higher frequencies ranging from the UHF band up ...

This paper presents a novel design of an electric coupling structure for a substrate-integrated waveguide (SIW) bandpass filter, which exhibits flexible characteristics, sharp roll-off, and high ...

Sub-wavelength grating (SWG) metamaterials have garnered a great interest for their singular capability to shape the propagation of light. However, practical SWG implementations are limited by ...

A team of researchers at the University of California, Los Angeles (UCLA) has introduced a novel framework for designing and creating universal diffractive waveguides that can control the flow of ...

Cellular telephone technology takes advantage of a large number of frequency bands to provide ever-increasing bandwidth for mobile use. Each of those bands needs a filter to keep its signals separate ...
