Accidental bound state in the continuum in a chain of dielectric disks Sidorenko, M. S. Sergaeva, O. N. Sadrieva, Z. F. Roques-Carmes, Charles Muraev, P. S. Maksimov, D. N. Bogdanov, A. A. Dielectric resonators are open systems whose eigenmodes couple to the radiation continuum resulting in nonzero radiation losses. For a long time, it was believed that only guided modes with frequencies below the light line were decoupled from the radiation continuum [1] . In the early 2000’s, several counterexamples of perfectly localized states – i.e. totally decoupled from the radiation continuum – at frequencies above the light line were proposed in dielectric gratings and photonic crystal waveguides [2] . Such states are known as bound states in the continuum (BIC) .
