(a) Derive the boundary condition on the tangential component of E, starting from Faraday's law in integral form. Assume time-independent fields. A microwave of frequency f = 3.5 MHz is propagating in the +z direction in a vacuum. It is normally incident upon the surface of a perfect conducting plane located at z = 0. The surface of the conductor lies on the xy-plane. The amplitude of the incident electric field is E0 and it is polarized in the x-direction. (b) State the vector relationship between the electric field E, magnetic field B and the propagation vector k. (c) Write down the incident and reflected electric and magnetic fields in complex phasor notation. (d) What is the value of the reflection coefficient R, given by the ratio of the complex amplitudes, R = E˜0r/E˜0i? (e) Given the attenuation coefficient, κ = ω√(μϵ/2 √(1+(σ/ϵω)^2 )-1). show that the skin depth is approximately inversely proportional to f^(1/2) for real conductors. State any assumptions used.
