Enhanced sensitivity of an all-dielectric refractive index sensor with optical bound state in the continuum
Dmitrii N. Maksimov, Valery S. Gerasimov, Andrey A. Bogdanov +1
The sensitivity of a refractive index sensor based on an optical bound state in the continuum is considered. Applying Zel'dovich perturbation theory we derived an analytic expressi…
Bound states in the continuum in periodic structures with structural disorder
Ekaterina E. Maslova, Mikhail V. Rybin, Andrey A. Bogdanov +1
We study the effect of structural disorder on the transition from the bound states in the continuum (BICs) to quasi-BICs by the example of the periodic photonic structure composed…
Bound States in the Continuum in Compact Acoustic Resonators
Ilya Deriy, Ivan Toftul, Mihail Petrov +1
We reveal that finite-size solid acoustic resonators can support genuine bound states in the continuum (BICs) completely localized inside the resonator. The developed theory provid…
Excitation of a bound state in the continuum via spontaneous symmetry breaking
Alexander Chukhrov, Sergey Krasikov, Alexey Yulin +1
Bound states in the continuum (BICs) are non-radiating solutions of the wave equation with a spectrum embedded in the continuum of propagating waves of the surrounding space. The c…
