A Random Field Theory of Electromagnetic Information [PDF]

open access: yesEntropy
As a rigorous and comprehensive foundation for electromagnetic information theory (EIT), we develop a general theory that elucidates the universal stochastic structure of radiated electromagnetic (EM) fields and induced currents in generic EM information

Compatibility Analysis Among Vector Magnetic Circuit Theory, Electrical Circuit Theory, and Electromagnetic Field Theory

open access: yesIEEE Access, 2023
Due to the presence of the new magnetic component of magductance (or magnetic-inductace), the traditional scalar magnetic circuit theory is evolved into the vector magnetic circuit theory.

Intrinsic Relations Between Transmission and Reflection in Metamaterials [PDF]

open access: yesMicromachines
Metamaterials possess high freedom on structural design, yet their ability to modulate electromagnetic waves is subject to intrinsic constraints that are independent of specific meta-atom geometries.

A comparision of Hodgkin-Huxley and soliton neural theories [PDF]

open access: yesAdvances in Radio Science, 2010
Hodgkin and Huxley were the pioneers to abstract biological neuron as an electric circuit and nerve signal as the voltage impulse. The Hodgkin-Huxley theory (Hodgkin and Huxley, 1952) has set the direction and defined the goals for much of the ensuing ...

Search for Manifestations of Spin–Torsion Coupling

open access: yesUniverse, 2023
We investigate the axial vector spin–torsion coupling effects in the framework of the Poincaré gauge theory of gravity with the general Yang–Mills type Lagrangian.

Dust grain dynamics due to nonuniform and nonstationary high-frequency radiations in cold magnetoplasmas [PDF]

open access: yesAnnales Geophysicae, 2006
A general nonlinear theory for low-frequency electromagnetic field generation due to high-frequency nonuniform and nonstationary electromagnetic radiations in cold, uniform, multicomponent, dusty magnetoplasmas is developed.

Rotation of electromagnetic fields and the nature of optical angular momentum [PDF]

open access: yes, 2010
The association of spin and orbital angular momenta of light with its polarization and helical phase fronts is now well established. The problems in linking this with electromagnetic theory, as expressed in Maxwell's equations, are rather less well known.

Relativistic theory of the asymmetric field

open access: yesRevista de Investigación de Física, 2022
In this paper, we have given a presentation of the relativistic theory of asymmetric field. It is our aim to present a theory of gravitation and electomagnetism by a generalization of the concepts and mathematical methods of the general relativity.

Electromagnetic oscillations of the Earth's upper atmosphere (review) [PDF]

open access: yesAnnales Geophysicae, 2010
A complete theory of low-frequency MHD oscillations of the Earth's weakly ionized ionosphere is formulated. Peculiarities of excitation and propagation of electromagnetic acoustic-gravity, MHD and planetary waves are considered in the Earth's ...
