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.

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.

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 ...

Modeling and Simulation of stochastically deformed Waveguides using Schelkunoff's Method [PDF]

open access: yesAdvances in Radio Science, 2018
This paper deals with the propagation of electromagnetic waves in cylindrical waveguides with irregularly deformed cross-sections. The general theory of electromagnetic waves is of high interest because of its practical use as a transmission medium ...
