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 ...

Abstract: The IEC 60153-2 and IEEE 1785.1 international standards for rectangular metallic waveguides are currently undergoing revision. Textbook derivations of the associated equations for the ...

Estimates are derived on the time and space derivatives of a shallow fluid flow in a channel of approximately rectangular cross section. These estimates depend upon the velocity and pressure being ...
