Suppose that an electromagnetic wave which is linearly polarized along the xâaxis is propagating in vacuum along the zâaxis. the wave is incident on a conductor which is placed at z > 0 region of the space. the conductor has conductivity Ï, magnetic permeability ” and electric permittivity Δ. (a) find the characteristic time for the free charge density which dissipates at the conductor. (b) write the maxwell equations and derive the wave equation for a plane wave propagating in a conductor. (c) find the attenuation distance at which the incident amplitude reduces to e ^â1 of its initial value. (d) find the electric and magnetic fields inside the conductor. 8 (e) find the power loss per area of the incident electromagnetic wave at the surface of conductor.
