Refraction of s - and p -polarized electromagnetic waves at the interface between a nonmagnetic insulator and an easy-axis centroantisymmetric antiferromagnet

Using the example of an easy-axis antiferromagnet with a magnetic structure of 4 z − 2 x + I − the effect of antisymmetric magnetoelectric interaction on the nature of the refraction of the bulk s - or p -polarized electromagnetic waves, incident from outside at any angle to the surface of the magnet, is studied analytically. The easy magnetic axis is collinear to the normal to the medium interface.
