Magnetic field polarization
Radiofrequency waves in lossy media Inductive effects through a cylindrical body

Let's now consider the wave inside the cylinder presented in the dual polarization of the previous one, where the electric field E _z is matched by a magnetic field H _z . By duality, the angular magnetic field H _φ is also matched by the angular electric field E _φ . The calculations presented in this paragraph endeavor to show that the current configuration of fields inside the cylinder can only be achieved in the presence of an inducing magnetic field H _zi parallel to the cylinder axis. It follows from these properties that the cylinder shown in figure
