Question

Electromagnetic theory 2

(a) Obtain the expressions for Ex and Ey for the transverse electric case and show that they satisfy the condition Ell *= 0 on the boundary.

(b) A rectangular metallic waveguide has dimensions, a = 3.0 cm and b = 4.0 cm. Find out the modes (TE and TM) in which a free space wavelength of 4.5 cm could propagate through it.

(c) A waveguide has an inside dimension of 6cm x 1cm. Find the first 3 modes and its cut-off frequencies. In the situation where you would want to have only one mode of propagation, what will be the proposed frequency range?

EII= E parallel
