A FEM-Green Approach for Magnetic Field Problems with Open Boundaries
Mathematics, 2021 A new finite element method/boundary element method (FEM/BEM) scheme is proposed for the solution of the 2D magnetic static and quasi-static problems with unbounded domains. The novelty is an original approach in the treatment of the outer region.

Magnetic field of rectangular current loop with sides parallel and perpendicular to the surface of high-permeability material [PDF]
Serbian Journal of Electrical Engineering, 2014 In this paper, method of current images is used to calculate magnetic field of a rectangular loop in presence of high-permeability material. We provide closed form description for the images of the current loop placed between two semi-infinite ...

On the Tree Gauge in Magnetostatics
J, 2022 We recall the classical tree-cotree technique in magnetostatics. (1) We extend it in the frame of high-order finite elements in general domains. (2) We focus on its connection with the question of the invertibility of the final algebraic system arising ...

Modeling Floating Potential Conductors Using Discontinuous Galerkin Method
IEEE Access, 2020 Isolated conductors appear in various electrostatic problems. In simulations, an equipotential condition with an undefined/floating potential value is enforced on the surface of isolated conductors.

Optimal Magnetic Sensor Vests for Cardiac Source Imaging
Sensors, 2016 Magnetocardiography (MCG) non-invasively provides functional information about the heart. New room-temperature magnetic field sensors, specifically magnetoresistive and optically pumped magnetometers, have reached sensitivities in the ultra-low range of ...
