(a) Most microwave ovens operate at 2.45 GHz. Assume that σ = 1.2 × 10⁶ S/m and μ_r = 500 for the stainless steel interior, and find the depth of penetration.

(b) Let E_s = 50 0◦ V/m at the surface of the conductor, and plot a curve of the amplitude of E_s versus the angle of E_s as the field propagates into the stainless steel.
