Question:
Dominant mode of propagation in a rectangular wave guide is ________.
Dominant mode of propagation in a rectangular wave guide is ________.
Show Hint
In rectangular waveguides, TE10 is the dominant mode. It’s the easiest to excite and has the lowest cutoff frequency.

- TM20
- TE10
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Waveguide Modes:
Waveguides support TE (Transverse Electric) and TM (Transverse Magnetic) modes.
The dominant mode is the one with the lowest cutoff frequency.
TE10 is dominant because:
It has the lowest cutoff frequency in rectangular waveguides.
Electric field is transverse to direction of propagation (no E-field in direction of propagation).
Easy to excite and analyze.
