Power losses in circcular Waveguide
The theory and equations derived for TE and TM modes in rectangular waveguides are applicable to TE and TM modes in circular guides. The power losses for the TEM mode in coaxial lines can be computed from transmission-line theory by means of
For a low-loss conductor, the attenuation constant is given by :
With the help of thsese equations we can analyze the power losses in circular waveguide.
