Stability Constraints on Practical Implementation of Parity-Time-Symmetric Electromagnetic Systems
Recently, several applications leveraging unconventional manipulation of electromagnetic radiation based on parity-time symmetry have been proposed in the literature. Typical examples include systems with unidirectional invisibility and asymmetric refraction. Such applications assume an inherent sys...
