On the Relationship of Quantum Mechanics to Classical Electromagnetism and Classical Relativistic Mechanics

open access: yes, 2004
Some connections between quantum mechanics and classical physics are explored. The Planck-Einstein and De Broglie relations, the wavefunction and its probabilistic interpretation, the Canonical Commutation Relations and the Maxwell--Lorentz Equation may ...

Including electromagnetism in $K\to\pi\pi$ decay calculations

open access: yes, 2017
Because of the small size of the ratio A_2/A_0 of the I=2 to I=0 K -> pipi decay amplitudes (the Delta I=1/2 rule) the effects of electromagnetism on A_2 may be a factor of 20 larger than given by a naive O(alpha) estimate.

Formal analogies between gravitation and electrodynamics

open access: yes, 2008
We develop a theoretical framework that allows us to compare electromagnetism and gravitation in a fully covariant way. This new scenario does not rely on any kind of approximation nor associate objects with different operational meaning as it's sometime

AXION-ELECTROMAGNETIC WAVES [PDF]

open access: yesModern Physics Letters A, 2013
We extend the duality symmetry between the electric and the magnetic fields to the case in which an additional axion-like term is present, and we derive the set of Maxwell equations that preserves this symmetry. This new set of equations allows for a gauge symmetry extending the ordinary symmetry in the classical electrodynamics.

Alternative Input Architecture for Balanced Diplexers Based on Over-Coupled H-Shaped Resonators With Independent Dual-Band Response

open access: yesIEEE Access
A novel technique for designing balanced-to-balanced diplexers with enhanced common-mode rejection is presented. In this approach, the conventional T-junction typically used to feed the diplexer output channels is replaced by a pair of over-coupled H ...

Beyond Green’s Functions: Inverse Helmholtz and “Om” -Potential Methods for Macroscopic Electromagnetism in Isotropy-Broken Media

open access: yesPhotonics
The applicability ranges of macroscopic and microscopic electromagnetism are contrasting. While microscopic electromagnetism deals with point sources, singular fields, and discrete atomistic materials, macroscopic electromagnetism concerns smooth average

Ultra Wide X-Band Microwave Imaging of Concealed Weapons and Explosives Using 3D-SAR Technique

open access: yesInternational Journal of Antennas and Propagation, 2015
In order to detect and image concealed weapons and explosives, an electromagnetic imaging tool with its related signal processing is presented. The aim is to penetrate clothes and to find personal-born weapons and explosives under clothes. The chosen UWB

Galilean Covariance versus Gauge Invariance [PDF]

open access: yes, 2009
We demonstrate for the first time and unexpectedly that the Principle of Relativity dictates the choice of the "gauge conditions" in the canonical example of a Gauge Theory namely Classical Electromagnetism.

Controlling Electromagnetic Fields

open access: yesScience, 2006
Using the freedom of design that metamaterials provide, we show how electromagnetic fields can be redirected at will and propose a design strategy. The conserved fields—electric displacement field D , magnetic induction field B , and Poynting vector B —are all ...
