Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Abstract The directions of phase and group velocities of TE and TM polarization waves refracted at the interface between an isotropic dielectric and uniaxial crystal with magnetoelectric properties are investigated. The angles that determine the directions of phase and group velocities of TE and TM waves are obtained in analytical form in different directions of the incident wave vector. The results are analyzed for the case of uniaxial crystals without magnetoelectric properties.
