QUESTION 3 The magnetic field intensity of an electromagnetic wave propagating in a lossless medium with € = 4€0 and μ = μo is Ĥ(z, t) = 0.5 cos (10°t-kz+n/4) (²). Calculate propagation constant k () of the wave. [c = 3 x 108 m/sec] m m
QUESTION 4 Find the impedance of the lowest (or dominant) mode of a rectangular waveguide filled with dielectric material with 8, 9 and having dimensions a = 1 cm and b = 0.5 cm, to be used at 20 GHz. [phase velocity upo = c/√er]
