Part 5/8:
When examining the operation of a parallel plate capacitor, while it may be assumed that the vacuum between the plates behaves similarly to that of a dielectric material, this is not the case. Without the presence of polarizable particles, the electric field in vacuum does not initiate displacement currents comparable to those in materials like rubber or glass. This misconception has underpinned the conventional electromagnetic theories that attempt to align light and radio waves as electromagnetic phenomena.
