Exercise 45

A right-hand circularly polarized plane wave represented by the phasor

impinges normally on a perfectly conducting wall at z = 0.
a) Determine the polarization of the reflected wave.
b) Find the induced current on the conducting wall.
c) Obtain the instantaneous expression of the total electric intensity based on a cosine time reference.
