Differential Forms in Electromagnetic Theory
The differential forms research group at BYU is investigating the use of the calculus of
differential forms in teaching and research. Differential forms have been used to express
Maxwell's laws since early in this century, but many of the advantages of forms as a tool for
applied electromagnetics have only recently been discovered.
