“…It was shown that the MIT and MIA phenomena are observed near the Dirac points. Let us note, that all the works [51][52][53][54][55] deal with the case when the parameter of magneto-optical activity g is constant and is independent of wavelength. In this paper, we will discuss the possibility of observing Dirac points and lines and exceptional points and lines in magnetically active CLCs in the case when the parameter of magneto-optical activity g is function of wavelength.…”
