Electromagnetic flowmeters in multiphase flows [PDF]

open access: yes, 1993
The response of an Electromagnetic Flowmeter to a secondary, nonconducting phase in a continuous conducting phase is investigated. Experiments are carried out on a commercial 2" Foxboro flowmeter with sinusoidal mains field excitation and point ...

Pure electromagnetic-gravitational interaction in Hořava–Lifshitz theory at the kinetic conformal point

open access: yesEuropean 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 ...

Weak Turbulence and Quasilinear Diffusion for Relativistic Wave-Particle Interactions Via a Markov Approach

open access: yesFrontiers 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.

Fractal Clustering as Spatial Variability of Magnetic Anomalies Measurements for Impending Earthquakes and the Thermodynamic Fractal Dimension

open access: yesFractal 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 ...

The Spatial Singularity Expansion Method for Electromagnetics

open access: yesIEEE 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]

open access: yesEPJ 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 ...

Electromagnetic Transients in Multiconductor Transmission Lines

open access: yesJournal of Microwaves, Optoelectronics and Electromagnetic Applications, 2022
The theory of multiconductor transmission lines is based on the principle of superposition. According to this principle, any electric or magnetic field can be represented as the sum of individual electric or magnetic fields.

PERTURBATION THEORY FOR ELECTROMAGNETIC WAVE SCATTERING IN RANDOM LAYERED STRUCTURES [PDF]

open access: yes, 2010
The problem of electromagnetic wave scattering in 3-D random layered structures, is analytical treated by relying on original results of the Boundary Perturbation Theory (BPT) and Volumetric-Perturbative Reciprocal Theory (VPRT), whose structured ...
