The calculus of differential forms has been applied to electromagnetic field theory in several papers and texts, some of which are cited in the references. Despite this work, differential forms are underused in applied electromagnetics research, partly due to the abstract viewpoint used in most treatments. Differential forms have a simple and intuitive geometrical interpretation which allows problems to be attacked intuitively and sometimes solved before the formal details are developed. It has been known for decades that forms allow Maxwell’s laws to be written elegantly; we find that this is true of other expressions as well. Compared to the usual vector formulation, derivations are often cleaner and final results easier to apply, making the calculus of differential forms a natural tool for applied electromagnetics.
