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. http://www.ee.byu.edu/ee/forms/forms-home.html
