Suppose that an electromagnetic wave which is linearly polarized along the xโaxis is propagating in vacuum along the zโaxis. the wave is incident on a conductor which is placed at z > 0 region of the space. the conductor has conductivity ฯ, magnetic permeability ยต and electric permittivity ฮต. (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 ^โ1 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.
