Rectangular Waveguide Breakdown Power Formula

The waveguide is the hollow metallic structure used to carry EM waves from one point to another. The structure having a rectangular shape is referred to as a rectangular waveguide.

Power flow along the waveguide is given by the Poynting vector expression. Power transmitted in the waveguide is a function of the cross-sectional dimensions of the waveguide, as well as the cutoff frequency (fc) and the operating frequency of the waveguide. Hence, breakdown power also depends on these parameters.

The following equation or formula is used for the rectangular waveguide breakdown power calculator:
