A 60-MHz plane wave traveling in the +z-direction in dry soil with relative permittivity, εr =3.6 has an electric field polarized along the x-direction. Assuming dry soil to be approximately lossless, and given that the magnetic field has a peak value of 20 (mA/m) and that its value was measured to be 10 (mA/m) at t = 0 and x = 1.25 m. Develop complete expressions for the wave’s electric and magnetic fields.
