There is a close relationship between second-order elliptic equations and the governing equations of electromagnetism, but the lack of strong ellipticity introduces subtle new challenges.
In linear theories such as quantum mechanics and classical electromagnetism, the presence of singularities in reduced systems, and their consequences are understood.
Under the general relativistic formalism, electromagnetism in a moving medium can be described by replacing the medium with an optical metric.
Theoretical computational electromagnetism is a huge area and this article can cover only a fraction of it.
He likewise hoped that the unification of electromagnetism and gravitation would similarly yield particle-like solutions endowed with electric charge.
Although his primary research interest was the unification of electromagnetism and gravitation he was aware of other developments.
Others were concerned with specific research topics he had himself pursued, such as, for instance, vision, electromagnetism, and geometry.
From the experimentally measured reflectivity, electromagnetism allows calculating the conductivity of metallized water.
