We review the electromagnetic scalar and vector potentials from the point of view of the Generalized Fredholm Integral Equations. Then we revise two sensitive concepts as the retarded and advanced Green functions. Provided we have developed the appropriate desired equations; we go to the problem of left-hand materials conditions for optimized broadcasting. We give also an academic but simple example...
We recall some results about the confinement of electromagnetic field from the Fredholm's equations properties perspective. Then we review some relations between the Maxwell equations and the generalized Fredholm's equations and show the equivalence between these two points of view when we analyze the change in the broadcasting conditions from confined electromagnetic field to travelling waves, underlying...
Under the concept of the so called Resonant Technology, recently we had proposed a device that can transport a lot of different signals, all of them of similar frequencies although different recording time, packed around the resonant frequencies. With the aim to implement physically the device, we had developed an algorithm, which is inserted in a FPGA to build information packs and send it. Also,...
The very fast variations on the real propagation conditions for electromagnetic waves can be simulated by a plasma sandwich model consistent in three iterated plasma layers: unmagnetized-magnetized-unmagnetized, in which we can establish resonant conditions (left-hand material conditions) by tuning the magnetization and electric potential intensity. In this paper we show how to prevent drastically...
Electromagnetic Time Reversal Vector formalism [1, 2] can be employed not only to the purpose of achieve subwavelength focusing. We can go far away of this initial goal and take the formalism as the starting point for analyzing the behavior of discrete electromagnetic systems in a regime that represents special but interesting physical usefully situations. The advantage over other possible approximations...
We define, by a natural way, a velocity field at a space region occupied by an electromagnetic field. By using that velocity field we can obtain a relativistic expression for drift velocity of an electrically charged particle in presence of an electromagnetic field. Taking in account temporal components and the temporal space of the energy momentum tensor of electromagnetic field, and also his Lorentz...
