Avoidance of contradictions in derivation and in usage of the Maxwell stress tensor in electrical engineering lectures

International Journal of Electrical Engineering & Education, 2019
The Maxwell stress tensor has a great significance, for example for the calculation of forces in electromagnetic energy converters, and thus is standard content of advanced lectures during electrical engineering study. However, the derivation and understanding of it is difficult and there is standard literature that is not consistent and thus ...

The Maxwell stress tensor and the thermodynamics of the diffuse double layers at surfactant-loaded interfaces

Journal of the Chemical Society, Faraday Transactions 2, 1988
The stress tensor or its negative counterpart, the pressure tensor, is not uniquely defined for a small system of molecular dimensions. Hence there are several possible definitions of the local stress tensor, among them the well known Kirkwood–Buff and Irving–Kirkwood definitions.

Stress-tensor trace anomaly in a gravitational metric: General theory, Maxwell field

Physical Review D, 1977
The renormalization of the vacuum expectation value of the stress-energy tensor of a scalar field propagating in a curved space-time with an arbitrary metric was discussed in a previous paper. A new regularization scheme was introduced which employs a continuation in the dimensionality of space-time implemented with a proper-time representation of the ...

Force Calculations in 3-D Cylindrical Structures Using Fourier Analysis and the Maxwell Stress Tensor

IEEE Transactions on Magnetics, 2013
Analytical modeling is still a very effective manner to calculate the magnetic fields in permanent magnet devices. From these magnetic fields, device quantities, e.g. force, emf or inductance, can be calculated. This paper presents a semianalytical technique, based on a 2D Fourier series to represent the magnetic field, to describe the force components

Force calculation by Maxwell stress tensor in 3D hybrid finite element-boundary integral formulation

IEEE Transactions on Magnetics, 1990
The calculation of magnetic force by the Maxwell stress tensor in 3-D hybrid finite element-boundary integral formulation is presented. The Maxwell stress tensor is calculated on the boundary of the domain considered. One field component (tangential or normal depending on the use of the magnetic or the electric formulation) is calculated from the ...

Calculation of Optical Force at Nanoscale Using Finite Element Method and Maxwell Stress Tensor

2019 International Applied Computational Electromagnetics Society Symposium - China (ACES), 2019
The manipulations of nanoparticles based on the optical force can avoid mechanical damage to the targets, and the intensity of the optical force can be precisely controlled by the light source. In this paper, a numerical method combining finite element method (FEM) with Maxwell stress tensor (MST) method is presented to calculate the optical force ...

Modified method for computing the optical force of the plasmonics nanoparticle from the Maxwell stress tensor

Journal of the Optical Society of America B, 2016
By controlling the optical force, optical tweezers can manipulate many kinds of small particles without mechanical contact. In the theoretical analysis of the optical force, conventional methods are based on the integration of the Maxwell stress tensor over the outer surface of the particle, while the Maxwell stress tensor is determined by the ...

Reviewing the Forces of Electret Motors by Applying Maxwell Stress Tensor and Delta Function

Japanese Journal of Applied Physics, 1995
The forces exerted on the electret rotors of the conventional Gubkin- and Jefimenko-type electret motors and the intermediate-type motor have been derived systematically using the Maxwell stress tensor and delta function. The delta function is effective in deriving the force due to the edges of a pair of stator electrodes of the Gubkin-type motor.
