waveguide problem

[danai_pa]

A rectangular wave guide of dimensions a=5.08 cm and b=2.54 cm. If the frequency of operation when the wave guide is air filled is 5 GHz

a) Dtermine all the possible propagation modes in the wave guide (TE(mn) that can propagate through this waveguide)

b) Repeat part a) assuming that the wave guide is filled with a directric material of Ke=4

Anyone please suggest me
Thank you
