Problem-3
For a parallel plane waveguide, infinite in extent and with a spacing of 20 cm between the plates, calculate the
  1. phase velocity for TEM mode at all wavelengths
  2. cut-off wavelength for dominant TE mode
  3. phase velocity for dominant mode at 80% of cut-off wavelength
  4. reflection angle for the above frequency of operation
Solution
Here, d = 20 cm
 
Phase velocity for TEM mode is given as, Description: 44447.png
 
Cut-off wavelength for dominant mode is, Description: 44437.png
 
Phase velocity for dominant mode at 80% of cut-off wavelength is given as,
