engineering recuitment GATE ECE 2023-24 Test Series Electromagnetic Theory Waveguides and Guided Waves Rectangular Waveguide
A material is characterised by σ =0, ϵ = 4ϵ0 and μr = 1
A rectangular waveguide with dimensions a = 2.5 cm and b = 1 cm is to operate below 9 GHz.
1
The waveguide can transmit 2 TE modes and 1 TM mode if the guide is filled with air.
2
The waveguide can transmit 5 TE modes and 2 TM modes if the guide is filled with the material.
3
The waveguide can transmit 1 TE modes and 0 TM mode if the guide is filled with air.
4
The waveguide can transmit 4 TE modes and 1 TM mode if the guide is filled with the material.
