Matthew Nojimu Olanipekun Sadiku from the Prairie View A&M University, Cypress, TX was named Fellow of the Institute of Electrical and Electronics Engineers (IEEE) in 2013 [1] "for contributions to computational electromagnetics and engineering education". He is a co-author of the textbook Fundamental of Electric Circuits with Charles K. Alexander.
Continuous charge distribution. The volume charge density ρ is the amount of charge per unit volume (cube), surface charge density σ is amount per unit surface area (circle) with outward unit normal nĚ‚, d is the dipole moment between two point charges, the volume density of these is the polarization density P.
David Keun Cheng (January 10, 1918 – August 22, 2012) was a Chinese-born Professor of Electrical Engineering. He was known for his work in the field of electromagnetics. [1] [2] His 1983 undergraduate textbook Field and Wave Electromagnetics has been cited in more than 4000 publications [3] and in 2016 is in the collections of about 500 libraries around the world.
According to a 2023 lecture titled What Physicists Don't Know About Electromagnetism given by the theoretical physicist Hans Schantz [162] and based on the comparison of textbooks Electromagnetic Theory by Julius Stratton and Classical Electrodynamics by John Jackson, Schantz argues "today's physicists who are educated using curriculum out of ...
In a linear, macroscopic theory, the influence of matter on the electromagnetic field is described through more general linear transformation in the space of 2-forms. We call : the constitutive transformation. The role of this transformation is comparable to the Hodge duality transformation.
The theory provides a description of electromagnetic phenomena whenever the relevant length scales and field strengths are large enough that quantum mechanical effects are negligible. For small distances and low field strengths, such interactions are better described by quantum electrodynamics which is a quantum field theory.
A theory of electromagnetism, known as classical electromagnetism, was developed by several physicists during the period between 1820 and 1873, when James Clerk Maxwell's treatise was published, which unified previous developments into a single theory, proposing that light was an electromagnetic wave propagating in the luminiferous ether.

Galilean electromagnetism is a formal electromagnetic field theory that is consistent with Galilean invariance.Galilean electromagnetism is useful for describing the electric and magnetic fields in the vicinity of charged bodies moving at non-relativistic speeds relative to the frame of reference.
