This article introduces a new class of electromagnetic materials: unimodular media. Unimodular media are magnetoelectric bi-isotropic media for which the determinant of the normalized four-parameter constitutive material matrix is unity. As special cases of such media are perfect electric conductor, perfect magnetic conductor, perfect electromagnetic conductor, simple skewon media, and simple isotropic media with unit refractive index. The essential parameters in the description of unimodular media (strength of impedance, degree of magnetoelectricity, angle of reciprocity) allow for illuminating visualizations of this class of materials.
