An electromagnetic wave travels from point xA to point xB through a medium with attenuation coefficient α (Neper/m). The electric field magnitude at point xA is 500 V/m; and at point xB is 5 V/m. The distance between these two points is 100 m. Calculate: i) the attenuation coefficient of the medium α (Np/m) ii) the shielding effectiveness of the medium in dB.
