New Framework to Study Electromagnetic Turbulence

Autor: Mario J. Pinheiro

Publikováno v: Magnetism, Vol 2, Iss 4, Pp 356-367 (2022)

Combining a current source involving vortical surface currents in the set of Maxwell’s equations offers a functional framework to address the complex phenomena of electromagnetic turbulence. The field structure equations exhibit fluid behavior with

Extended Field Interactions in Poisson’s Equation Revision

Autor: Mario J. Pinheiro

Publikováno v: Applied Sciences, Vol 14, Iss 5, p 1833 (2024)

This investigation introduces a new variational approach to refining Poisson’s equation, enabling the inclusion of a broader spectrum of physical phenomena, particularly in the emerging fields of spintronics and the analysis of resonant structures.

Modeling of Electrohydrodynamic (EHD) Plasma Thrusters: Optimization of Physical and Geometrical Parameters

Autor: Eduardo M. Calvo, Mario J. Pinheiro, Paulo A. Sá

Publikováno v: Applied Sciences, Vol 12, Iss 3, p 1637 (2022)

This work aims to optimize a previous self-consistent model of a single stage electrohydrodynamic (EHD) thruster for space applications. The investigated parameters were the thruster performance (propulsion force T, the thrust to power ratio T/P, the

A reformulation of mechanics and electrodynamics

Autor: Mario J. Pinheiro

Publikováno v: Heliyon, Vol 3, Iss 7 (2017)

Classical mechanics, as commonly taught in engineering and science, are confined to the conventional Newtonian theory. But classical mechanics has not really changed in substance since Newton formulation, describing simultaneous rotation and translat

Reassessment of the Concept of Momentum in Econophysics

Autor: Mario J. Pinheiro, Mario Rodrigo Afonso Pinheiro

Publikováno v: European Journal of Applied Physics. 3:25-35

We examine the most basic feature of the economic process - momentum - under the point of view of analogies with physical laws, as they were reformulated recently [1]. Our approach is applied with minimal assumptions and we conclude that the inclusio
