Maxwell's equations are a set of four differential equations that form the theoretical basis for describing classical electromagnetism: Gauss's law: Electric charges produce an electric field. The electric flux across a closed surface is proportional to the charge enclosed. Gauss's law for magnetism: There are no magnetic monopoles. The magnetic flux across a closed surface is zero.
Augmented electric- and magnetic-field integral equations, which preserve the basic simplicity, solution capability, and pure electric- and magnetic-field character of Maue's original integral equations, are introduced to eliminate the spurious resonances from the exterior solution of the original integral equations.

Sep 17, 2015 We know how electromagnetic waves travel through space: they do so because of the mechanism described in Maxwell’s equation: a changing magnetic field causes a changing electric field, and a changing magnetic field causes a (changing) electric field, as illustrated below.

Electrically charged particles such as Electrons and Protons carry electric, E, and magnetic, B, fields. In addition to these fields, Quantum Mechanics (QM) endows these particles with an `arcane and spooky' field --- the wavefunction. This wavefunction of QM is not only assumed to be separate but distinct from the electromagnetic field. We herein upend this view by demonstrating otherwise.

Whenever the magnetic field though any loop changes, and electric field circulates around the loop. Faraday's law states that the magnitude of the circulation of the electric field E around any closed loop is equal to the magnitude of the RATE OF CHANGE of the magnetic flux through the area enclosed by the loop.. Another of Maxwell's equations is the Ampere-Maxwell law.

For example, we do not yet know how the electric and magnetic fields themselves transform under a LT! Let us then reformulate our basic equations in 4-tensor form. We will make the equations themselves 4-scalars, 4-vectors, or 4-tensors of higher rank so that we can simply look at them and deduce their transformation properties.
