1. A 1-MHz plane wave is incident from air on an infinite copper sheet. If the amplitude of the incident E-field is 100 V/m, find τ, Γ, δ and the magnitude of electric and magnetic fields at a distance of one skin depth into the copper.

2. The electric field intensity of a uniform plane wave propagating in free space is known to be 377e^-j0.866ze^-j0.5y a_x V/m. It strikes a dielectric medium (ε_r = 9) at 30° with respect to the normal to the plane interface. Determine

(a) the frequency of the wave,

(b) expressions for the E and H fields in both media, and

(c) the average power density of the wave in the dielectric medium. Assume that the permeability of the medium is the same as that of free space.
