Bound states in the continuum (BIC) accompanied by avoided crossings in leaky-mode photonic lattices

open access: yesNanophotonics, 2020
When two nonorthogonal resonances are coupled to the same radiation channel, avoided crossing arises and a bound state in the continuum (BIC) appears with appropriate conditions in parametric space. This paper presents numerical and analytical results on
