engineering recuitment GATE ECE 2023-24 Test Series Electromagnetic Theory Waveguides and Guided Waves Rectangular Waveguide
In a waveguide, the guide wavelength λg for m, n > 1, TEmn and TMmn modes at frequency above the cut-off follows the relation
1
(λg) TEmn < (λg)TMmn
2
(λg) TEmn > (λg)TMmn
3
(λg) TEmn = (λg)TMmn
4
The relation depends on the specific values of m and n
