The main advantages of this evolution should be felt in computational electromagnetism. It may also shed some new light on the concept of material isotropy. %K Maxwell equations %K differential forms %K Hodge operator %K anisotropic %K Metamaterials %U http://aemjournal.org/index.php/AEM/article/view/66
