Application of Herglotz's variational principle to electromagnetic systems with dissipation
This work applies the contact formalism of classical mechanics and classical field theory, introduced by Herglotz and later developed in the context of contact geometry, to describe electromagnetic systems with dissipation. ...
Numeric oscillations decreasing in electromagnetic transient simulations due to the variation of the circuit quantity used for the transmission line representation
(2011-12-01)
Studies of electromagnetic transients in transmission lines are greatly important for several analyses related to the power systems. Introducing these studies for undergraduate students, in this paper, it is presented an ...
Scattering of electromagnetic plane waves by a buried vertical dike
(Academia Brasileira de Ciências, 2003)
The complete and exact solution of the scattering of a TE mode frequency domain electromagnetic plane wave by a vertical dike under a conductive overburden has been established. An integral representation composed of ...
Electromagnetic characterization of recyclable polymer nanofibers based on PSU/carbonyl iron
(2019-01-01)
This study investigated and defined the optimal processing parameters for the electrospinning of polysulfone polymer solutions with N,N-dimethylacetamide. Variation of parameters such as solute concentration, electrical ...
Possible cosmological implications in electrodynamics due to variations of the fine structure constant
(Revista Mexicana de Física, 2009)
Electromagnetic field in Lyra manifold: a first order approach
(Sociedade Brasileira de Física, 2005-12-01)
We discuss the coupling of the electromagnetic field with a curved and torsioned Lyra manifold using the Duffin-Kemmer-Petiau theory. We will show how to obtain the equations of motion and energy-momentum and spin density ...
Spatial modulation of the electromagnetic energy transfer by excitation of graphene waveguide surface plasmons
(IOP Publishing, 2019-03-13)
We theoretically study the electromagnetic energy transfer between donor and acceptor molecules near a graphene waveguide (WG). The surface plasmons (SPs) supported by the structure provide decay channels which lead to an ...
