Answer to Question #87974 in Electricity and Magnetism for Sridhar

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
