Optically transparent antennas are being actively developed for various industrial applications; however, their widespread deployment is often limited by low radiation efficiency. Improving efficiency ...

Abstract: Proposed work presents narrow bandpass waveguide filter in Ku band. The Filter design is based on the use of small irises structure, in the transverse planes of the standard (WR-62) ...

Abstract: In this paper, the microwave equivalent reflection coefficient calculation model in the multilayer medium of cable termination is established, and the reflection coefficients of various ...

In this paper, a piecewise sine waveguide (PWSWG) is proposed as the slow-wave structure (SWS) to develop high-power terahertz (THz) traveling wave tubes (TWTs). The PWSWG is an improvement over the ...

A bilayer metamaterial to realize the broadband transmission in a terahertz (THz) filter was proposed, whose periodic unit structure consists of two rectangular apertures. The broadband consisting of ...

We propose a hybrid circuit for spoof surface plasmon polaritons (SPPs) and spatial waveguide modes to develop new microwave devices. The hybrid circuit includes a spoof SPP waveguide made of two anti ...
