Electromagnetic Waves in Crystals: The Presence of Exceptional Points

Abstract

In article number 2300235, Chris Sturm presents a comprehensive discussion on exceptional points (EPs) in optically anisotropic materials, their occurrence, and properties as well as the properties of the electromagnetic waves propagating along such EPs. The presence of such EPs, their spatial and spectral distribution in bulk, and semi-infinite and finite crystals are discussed.
