5. Consider two regions in space filled with air for 2 <0, while the region for which 2 > 0) is filled with a perfect conductor. A right handed circularly polarized plane wave propagating through the z <0 air region, described by the phasor Ę; = E. (Å - jỹ)e-382 [V/m] is impinging normally on the perfectly conducting wall at z=0. (a) (3 points) Determine the phasor of the reflected wave.

(b) (2 points) What is the nature of the polarization of the reflected wave? (Circle ONE) (i) Linearly Polarized, (ii) Right handed circularly polarized, (iii) Left handed circularly polarized, (iv) Elliptically polarized, (v) None of these (c) (2 points) Determine the phasor for the total magnetic field for z <0. (d) (2 points) Determine the phasor for the sheet current density, Js, on the conducting wall.

(e) (2 points) Determine the phasor for the surface charge density P, at the surface of the wall.
