Covariant formulation of at finite speed propagating electric interaction of moving charges in Euclidean geometry
Maxwell's electrodynamics postulates the finite propagation speed of electromagnetic (EM) action and the notion of EM fields, but it only satisfies the requirement of the covariance in Minkowski…

Electromagnetic induction: physics, historical breakthroughs, epistemological issues and textbooks
The discovery of Electromagnetism by Oersted (1820) started an 'extraordinary decennium' ended by the discovery of electromagnetic induction by Faraday (1831). During this decennium, in…

Surface electromagnetic waves at gradual interfaces between lossy media
A low loss propagating electromagnetic wave is shown to exist at a gradual interface between two lossy conductive media. The electromagnetic frequency range of this phenomenon may span from UV optics…

Electromagnetic Scattering by Networks of High-Permittivity Thin Wires
The electromagnetic scattering from interconnections of high-permittivity dielectric thin wires with sizes smaller than (or almost equal to) the operating wavelength is investigated. A simple lumped…

Excitation of forward and backward surface waves in a negative-index metamaterial
We study beam transmission and refection resulting from the resonant excitation of forward and backward surface waves in a metamaterial. We predict that exciting these waves at an interface this…

Casimir-Lifshitz forces and plasmons in a structure of two dielectric rods: Green's function method of electrodynamics
A new model for calculating the Casimir-Lifshitz force per unit length for two dielectric rods is proposed, based on the Green function method of classical electrodynamics and the Lorentz model for…

Cloaking, Trapping and Superlensing of Lamb Waves with Negative Refraction
We report on experimental and numerical implementations of devices based on the negative refraction of elastic guided waves, the so-called Lamb waves. Consisting in plates of varying thickness, these…

Can a single PDE govern well the propagation of the electric wave field in a heterogeneous medium in 3D?
It is demonstrated in this paper that the propagation of the electric wave field in a heterogeneous medium in 3D can sometimes be governed well by a single PDE, which is derived from the…

Polarization singularities and Möbius strips in sound and water-surface waves
We show that polarization singularities, generic for any complex vector field but so far mostly studied for electromagnetic fields, appear naturally in inhomogeneous yet monochromatic sound and…

A conjecture of thermo-gravitation based on geometry, classical physics and classical thermodynamics
One of the goals that physicists have been pursuing is to get the same explanation from different angles for the same phenomenon, so as to realize the unity of basic physical laws. Geometry,…
