P.8-12 The magnetic field intensity of a linearly polarized uniform plane wave propagating in the + y-direction in seawater [e, = 80, ,= 1, o = 4 (S/m)] is H=a₂0.1 sin (10¹⁰nt - n/3) (A/m) at y = 0. a) Determine the attenuation constant, the phase constant, the intrinsic impedance, the phase velocity, the wavelength, and the skin depth. b) Find the location at which the amplitude of H is 0.01 (A/m). c) Write the expressions for E(y, t) and H(y, t) at y = 0.5 (m) as functions of t.
