Question: 2 transverse field components inside a rectangular waveguide are given...

Question details

2. Transverse field components inside a rectangular waveguide are given below: A COS inCoS cos bk2 -A sin cos r bk A cos sin yak ta You are required to find the mode of propagation, whether it is TM or TE Let us take it as TX mn(a) If X = M what is the dominant mode? (b) If X = E what is the dominant mode? (c) Show that TX, , cannot exist. (d) Show that TX on cannot exist. (e) What is X, Mor E? () Find the dominant mode for the above field configuration. (g) Write an expression for H (h) With the help of a diagram briefly explain how the dominant mode can be excited in the waveguide.
