A right hand circularly polarized plane wave represented by the phasor E(z) = Egelo(ax - jy)e-1Bz Impinges normally on a perfectly conducting wall at z = 0. (a) Determine the polarization of the reflected wave and identify wave kind of plane wave it is. (b) Find the distance from the wall, at which the null electric field point is closest to the wall. (c) Find the induced current on the conducting wall. (d) Obtain the instantaneous expression of the total electric intensity based on a cosine time reference.
