Question
A smooth plane wave given Ei (z) = ax20e – j3z (V / m)
in air comes perpendicular to the interface with a lossy
medium with a dilution constant of 5 and a loss tangent
of 0.6 at z = 0.
a) Find the electric field strengths and the phasor
expressions of the magnetic field strengths of the
reflected and transmitted wave, (Find the phasor
expressions Er (z), Hr (z), Et (z), Ht (z)).
b) What is the standing-wave ratio (S) of the wave in
the air?
c) Find the time-average Poynting vector expressions in
air and lossy medium.
