1) The electric field component of a uniform plane VLF electromagnetic field vertically down in the +z direction in the ocean (o = 4(S / m),ɛ, =81,µ, =1) is given by E(z,1)= â¸E¸ez cos(67 ×10°t – Bz) where E, is the electric field amplitude at z=0. Find: a) The attenuation constant and the phase constants, b) The skin depth, c) The wavelength, the phase velocity, the intrinsic impedance and compare them to their values in air, d) The instantaneous expression for the corresponding magnetic field intensity.
