Wave Propagation in Periodic Metallic Structures with Equilateral Triangular Holes
(MDPI, 2020)
This paper studies wave propagation in a periodic parallel-plate waveguide with equilateral triangular holes. A mode-matching method is implemented to analyze the dispersion diagram of the structure possessing glide and ...

Study of forward and backward modes in double-sided dielectric-filled corrugated waveguides
(MDPI, 2021)
This work studies the propagation characteristics of a rectangular waveguide with aligned/ misaligned double-sided dielectric-filled metallic corrugations. Two modes are found to propagate in the proposed double-sided ...

On the Benefits of Glide Symmetries for Microwave Devices
(IEEE Computer Society, 2021)
The presence of glide symmetries in periodic structures can introduce beneficial modifications in their electromagnetic properties. The difference between glide and non-glide periodic structures is due to the distinctive ...

Dispersion analysis of twist-symmetric dielectric waveguides
(MDPI, 2021)
We propose a circular twist-symmetric dielectric waveguide that is polarization-selective. In the practical implementation of optical fibers, a selective circular polarization is more convenient than its linearly polarized ...
