1. To measure the phase velocity in a medium, especially if it is not vacuum, is rather difficult. Instead, it is proposed to proceed as follows: 1. Generate an electric field intensity in the medium with permeability μ and permittivity ε at some arbitrary frequency assuming that this is a plane wave. Assume a lossless medium. Measure the amplitude of the electric field intensity E. 2. Measure the amplitude of the magnetic flux density B, produced by the electric field...
