Abstract: Rectangular waveguides are an essential tool for measuring the intrinsic complex properties of simple dielectric media. This is because rectangular waveguides have a simple geometry, high ...
Abstract: This Waveguides transport high-frequency microwave signals efficiently with no major loss in signal power. A waveguide with a circular/rectangular cross-section operates on different ...
The first theoretical models of the propagation of an electromagnetic field in a waveguide date back to the second half of the 19th century (Hertz, Debye, Rayleigh). The technological fallout for long ...
