Question

For TE10 mode for the wave guide is filled with air and broader dimension of the wave guide is 2cm then the. Cut off frequency?
Ans: 7.5GHz

Answer 1

The cutoff frequency for TE 10 mode of propagation in a rectangular wave guide is given by formula

$$f=\frac {1}{2a} \sqrt{ɛμ} (1)$$

where a is the broader dimension of the wave, ɛ is the electric constant, μ is magnetic constant

Using (1) we got:

f=7.5 GHz

Answer:

7.5 GHz
