The electromagnetic form factor is extracted from both components of the electromagnetic current: J+ and J− with a pseudo-scalar coupling of the quarks to the kaon. In the case of J+ there is no pair term contribution in the Drell-Yan frame (q+ = 0). However, J− component of the electromagnetic current the pair term contribution is different from zero and is necessary include it to preserve the...

In a previous work [1] a theory of gravitation based on a nonsymmetric metric was formulated (pure gravitation with no association of the antisymmetric part of the metric to the electromagnetic eld strength). The sources of the metric eld are the matter energymomentum tensor T and the matter fermionic particle number current density S . This is a conserved current with particle number fermionic...

The aim of this review was to assess the current viable technologies for wireless power delivery and data transmission through metal barriers. Using such technologies sensors enclosed in hermetical metal containers can be powered and communicate through exterior power sources without penetration of the metal wall for wire feed-throughs. In this review, we first discuss the significant and essen...

In the framework of the teleparallel equivalent of general relativity, we study the dynamics of a gravitationally coupled electromagnetic field. It is shown that, besides being able to be minimally coupled to torsion, the electromagnetic field, through its energy–momentum tensor, is also able to produce torsion. Furthermore, it is shown that this kind of coupling of the electromagnetic field wi...

Matrix optics is applied to a class of random, in time and space, electromagnetic pulsed beam-like (REMPB) radiation interacting with linear optical elements. A 6×6 order matrix describing transformation of a six-dimensional state vector including four spatial and two temporal positions within the field is used to derive conditions for spatio-temporal coupling. An example is included which deal...

Electromagnetic wave propagation is usually reciprocal. However, in magneto-optical or gyromagnetic media, the propagation can be nonreciprocal. This effect has contributed to many important components in telecommunication systems, such as isolators and circulators. Recently, it has even been demonstrated that on the surface of magneto-optical or gyromagnetic media, electromagnetic waves can pr...

This paper presents an integrated electromagnetic and thermal model for the microwave processing offood packages. The model is developed by combining the edge finite element formulation of the 3-D vector electromagnetic field in the frequency domain and the node finite element solution of the thermal conduction equation. Both mutual and one-way coupling solution algorithms are discussed. Mutual...

We experimentally observed a new topological symmetry in optical composites, namely, metamaterials. While it is not found yet in nature materials, the electromagnetic Möbius symmetry discovered in metamaterials is equivalent to the structural symmetry of a Möbius strip, with the number of twists controlled by the sign change of the electromagnetic coupling between the meta-atoms. We further dem...
