engineering recuitment GATE ECE 2023-24 Test Series Electromagnetic Theory Waveguides and Guided Waves Rectangular Waveguide
For a wave propagating in an air-filled rectangular waveguide.
1
The guided wavelength is always less than the free-space wavelength.
2
The phase velocity is linear function of the operating frequency
3
The ratio of the transverse magnetic field to the transverse electric field is called waveguide impedance
4
The wave impedance can be less than or greater than the free space impedance
