Electromagnetic Green Functions Using Differential Forms

J. Electromagn. Waves and Appl., vol. 10, no. 3, pp. 427–438, 1996.
Authors redevelop the scalar and dyadic Green functions of electromagnetic theory using differential forms. The Green dyadic becomes a double form, which is a differential form in one space with coefficients that are forms in another space, or a differential form-valued form. The results presented here correspond closely with the usual dyadic treatment, but are clearer and more intuitive.
