Multiple Exceptional Points in APT–Symmetric Cantor Multilayers

Multiple Exceptional Points in APT–Symmetric Cantor Multilayers

In this study, we explore the anisotropic reflection of light waves around the exceptional points (EPs) in anti-parity-time−symmetric (APT−symmetric) Cantor dielectric multilayers. This one-dimensional fractal structure governed by the Cantor substitution law is modulated to satisfy APT symmetry. Th...
