A series of avoided crossings of resonances in the system of several different dielectric resonators results in giant Q-factors
Konstantin Pichugin, Almas Sadreev, Evgeny Bulgakov
We perform optimization of Q-factor in the system of freestanding three/four/five/six coaxial subwavelength dielectric disks over all scales. Each parameter contributes almost one…
Super bound states in the continuum through merging in grating
Evgeny Bulgakov, Galina Shadrina, Almas Sadreev +1
Bound states in the continuum (BICs) in gratings composed of infinitely long silicon rods of rectangular cross-section are considered. We reveal merging off- Friedrich-Wintgen B…
Super quasi-bound state in the continuum
Zhanyuan Zhang, Evgeny Bulgakov, Konstantin Pichugin +3
Avoided crossing of resonances and merging multiple bound states in the continuum (BICs) are parallel means for tailoring the physical properties of BICs. Herein, we introduce a ne…
Desktop laboratory of bound states in the continuum in metallic waveguide with dielectric cavities
Evgeny Bulgakov, Artem Pilipchuk, Almas Sadreev
We consider dielectric cavities whose radiation space is restricted by two parallel metallic planes. The TM solutions of the Maxwell equations of the system are equivalent to the s…
Degenerate bound states in the continuum in square and triangular open acoustic resonators
Almas Sadreev, Evgeny Bulgakov, Artem Pilipchuk +2
We consider square and equilateral triangular open acoustic resonators with the and symmetries, respectively. There is an unique property of square and triangular…
A General Framework of Bound States in the Continuum in an Open Acoustic Resonator
Lujun Huang, Bin Jia, Artem S Pilipchuk +11
Bound states in the continuum (BICs) provide a viable way of achieving high-Q resonances in both photonics and acoustics. In this work, we proposed a general method of constructing…
