Matter-field theory of the Casimir force

, 1998
A matter-field theory of the Casimir force is formulated in which the electromagnetic field and collective modes of dielectric media are treated on an equal footing.

Electrodynamic Contact Bounce Induced by Fault Current in Low-Voltage Relays

Energies, 2019
Due to fault currents occurring in electrical installations, high electromagnetic force values may be induced in current paths of low-voltage electromagnetic relays. This force may lead to an electromagnetic bounce that will further result in an electric

Obtaining Maxwell's equations heuristically

, 2012
Starting from the experimental fact that a moving charge experiences the Lorentz force and applying the fundamental principles of simplicity (first order derivatives only) and linearity (superposition principle), we show that the structure of the ...
