Question

In rectangular waveguides, the dimensions a and b represent the

(a) Broad wall dimensions

(b) Broad wall and side wall dimension respectively

(c) Side wall and broad wall dimension respectively

(d) Side wall dimensions

I had been asked this question in an online quiz.

My question is based upon Properties of Waveguides in chapter Waveguides of Electromagnetic Theory

Answer 1

Right answer is (b) Broad wall and side wall dimension respectively

Easiest explanation: In rectangular waveguide, the a parameter is the broad wall dimension of the waveguide and the b parameter is the side wall dimension of the waveguide. Always, a > b in a waveguide.
