Variation of the magnetic field at different positions and conditions within a complete period. (a) Magnetic field components at positions above and beneath the material respectively. Black and red curves represent the x and y components of magnetic field above the material. Blue and green curves represent the x and y components of magnetic field beneath the material. (b) Magnetic field vector above and beneath the material at four moments within a period. (c) Comparison of the magnetic field rotation of two waves incident in opposite directions.
