The cut off frequency of a rectangular waveguide of dimensions 3 cm x 1.5 cm is(a) 12 GHz(b) 6 GHz(c) 4 GHz(d) 5 GHzThis question was posed to me during a job interview.This question is from Transverse Electric Waves(TE) topic in division Waveguides of Electromagnetic Theory

Answer»

Right choice is (d) 5 GHz

For explanation: The cut off FREQUENCY in dominant mode will be fc = mc/2a. On substituting for c = 3 x 10^8 and a = 0.03, we get the cut off frequency as 5 GHz.
