In recent years, research on singularities called exception points (EPs) peculiar to non-Hermitian systems has been active. Especially, an EP sensor has attracted much attention because it realizes a high-sensitivity sensor in a small perturbation region by utilizing the sensitivity of the EP state. While conventional EP sensors perform sensing by obtaining changes in resonance frequency, we propose a new type of EP sensor that uses the eigenpolarization state of Jones matrix.
