Electrodynamics with a general local and linear constitutive law involves a constitutive tensor of 36 independent parameters for electromagnetic media. This tensor is irreducibly decomposed into three independent sets of parameters: the principal part of 20 components (known as the bianisotropic media), the axion part of 1 component and the skewon part of 15 independent components. The latter set...
Da Rocha and Rodigues (RR) claim (i) that in classical electrodynamics in vector calculus the distinction between polar and axial vectors and in exterior calculus between twisted and untwisted forms is inappropriate and superfluous, and (ii) that they can derive the Lorentz force equation from Maxwell's equations. As to (i), we point out that the distinction of polar/axial and twisted/untwisted derives...
