A fundamental limit on the performance of geometrically-tuned planar resonators [PDF]
, 2011 Geometric frequency tuning in planar electromagnetic resonators is common in many applications. It comes, however, at a penalty in the resonance quality, Q0. The literature traces the causes of such penalty often in terms of the shortcomings in the added

Relativistic x-ray free-electron lasers in the quantum regime [PDF]
, 2012 We present a nonlinear theory for relativistic x-ray free-electron lasers in the quantum regime, using a collective Klein-Gordon (KG) equation (for relativistic electrons), which is coupled with the Maxwell-Poisson equations for the electromagnetic and ...

Frontiers in Astronomy and Space Sciences, 2022 We derive weak turbulence and quasilinear models for relativistic charged particle dynamics in pitch-angle and energy space, due to interactions with electromagnetic waves propagating (anti-)parallel to a uniform background magnetic field.

Electromagnetic Properties of Neutrinos
Advances in High Energy Physics, 2012 In this paper, we discuss the main theoretical aspects and experimental effects of neutrino electromagnetic properties. We start with a general description of the electromagnetic form factors of Dirac and Majorana neutrinos.

European Physical Journal C: Particles and Fields, 2020 We introduce the electromagnetic-gravitational coupling in the Hořava–Lifshitz framework, in $$3+1$$ 3+1 dimensions, by considering the Hořava–Lifshitz gravity theory in $$4+1$$ 4+1 dimensions at the kinetic conformal point and then performing a Kaluza ...

Fractal and Fractional, 2022 Several studies focusing on the anomalies of one specific parameter (such as magnetic, ionospheric, radon release, temperature, geodetic, etc.) before impending earthquakes are constantly challenged because their results can be regarded as noise, false ...

Creation of a system for automatic monitoring of electromagnetic effects on biological and technical systems [PDF]
BIO Web of Conferences, 2022 Using a digital “twin” of a convergent biological and technical supersystem of a certain region to develop measures to ensure environmental safety is because of the need to analyze and predict processes and the level of electromagnetic pollution of the ...

The Spatial Singularity Expansion Method for Electromagnetics
IEEE Access, 2019 We develop a general singularity expansion method (SEM) focused on the spatial structure of electromagnetic fields and currents. In contrast to the traditional temporal SEM, where complex analytical continuation is performed on the forward Green's ...

Quantum spin dynamics in external classical fields [PDF]
EPJ Web of Conferences, 2019 We study the quantum and classical dynamics of spinning particles in the framework of the general-relativistic covariant Dirac theory. The exact Foldy-Wouthuysen transformation for the most general case of a fermion in arbitrary configurations of the ...

Anomalous magnetic moment of an electron near a dispersive surface [PDF]
, 2013 Changes in the magnetic moment of an electron near a dielectric or conducting surface due to boundary-dependent radiative corrections are investigated. The electromagnetic field is quantized by normal mode expansion for a nondispersive dielectric and an ...
