摘要：

In this letter we discuss a phase transition-like anomalous behavior of Faraday rotation angles in a simple parity-time (PT) symmetric model with two complex -potential placed at both boundaries of a regular dielectric slab. In anomalous phase, the value of one of Faraday rotation angles turns negative, and both angles suffer spectral singularities and yield strong enhancement near singularities. (c) 2022 The Authors.
