Q1. A 10 cm length of a K-band (a = 1.06 cm and b = 0.43 cm) copper ( = 5.8x107) waveguide is filled with a dielectric material with &-2.25 and tand = 0.0015. If the operating frequency is 15 GHz, find (1) the first three propagating modes and their cutoff frequencies (2) the total loss through the guide.
