The magnetic field of a uniform plane wave propagating in the +Y direction in sea water {ɛ, = 100, µ, = 1,0 = 4} at y = 0 is H = a, cos(101ºn t – 0. 5ny) (A/m). Determine: a) The attenuation constant, the phase constant and the intrinsic impedance b) The phase velocity, the wavelength and the skin depth c) Write the expressions of E(y, t) & H(y,t)at y = 0.75 (m)
