9. What is degenerate mode in waveguide.
In a waveguide when two or more modes have the same cut off frequency then they are said to be degenerate modes. In a rectangular waveguide the TEmn and TMmn with m ≠ 0 and n ≠ 0 are degenerate modes. For a square waveguide for which a = b, all the TEpq, TEqp, TMpq, TMqp modes are degenerat...

8. what is dominant mode in waveguides
For a waveguide the dominant mode is the mode with the lowest cut off frequency. Single mode propagation reduce losses, so we use dominant mode propagation.The waveguide can be operated only in the dominant mode for a certain range of frequency, this range of frequency extend from cut off frequency...
7. what are modes in waveguides
Lets explain what are modes in waveguide mean.For every type of waveguide the electromagnetic waves inside the waveguide can have an infinite number of distinct electromagnetic field patterns or configurations, these distribution of electric and magnetic fields in a waveguide is called modes. The...

6. What is a waveguide. Explain?
A wave-guide is a hollow conducting pipe, of uniform cross-section, used to transport high frequency electromagnetic waves (generally, in the microwave band) from one point to another. The main advantage of wave-guides is their relatively low level of radiation losses (since the electric and magnetic...

5. Compare waveguides and two wire transmission lines
Here we are comparing waveguides and two wire transmission lines. ☞ For frequencies higher than 3 GHZ, the transmission of electromagnetic waves along transmission lines and cables is not possible because of high loss, here a metallic tube can be used to transmit electromagnetic waves. ☞ A hollow...
