I am talking about some very specialised results in an application area. Not Electro Magnetism which I believe you are referring to? The formulation of EM with antisymmetric field tensors (which is the same thing as a bivector) is certainly very old and absolute standard in the physics curriculum. And I certainly was taught the definition in terms of wedge products that is also given here in undergrad: https://en.wikipedia.org/wiki/Electromagnetic_tensor https://en.wikipedia.org/wiki/Electromagnetic_tensor (See the section: Relationship to the classic fields). Not sure what you are looking for beyond that?
