Variational Analysis of a Dually Polarized Waveguide Skew Loaded by Dielectric Slab

Walid Dyab, Ahmed Sakr, Mourad Ibrahim and Ke Wu Published in: IEEE Microwave and Wireless Components Letters ( Volume: 30, Issue: 8, August 2020) DOI: 10.1109/LMWC.2020.3004004 Abstract: An expression for the propagation constant, cutoff frequency, and associated fields of the first two modes in a waveguide filled with a tilted slab of the dielectric is derived using the variational analysis. The […]
