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…
Tuning of bound states in the continuum by waveguide rotation
Almas F. Sadreev, Artem S. Pilipchuk, Alina A. Lyapina
We consider acoustic wave transmission in non axisymmetric waveguide which consists of cylindrical resonator and two semi-infinite cylindrical waveguides whose axes are shifted rel…
Bound states in the continuum in open acoustic resonators
A. A. Lyapina, D. N. Maksimov, A. S. Pilipchuk +1
We consider bound states in the continuum (BSC) or embedded trapped modes in two- and three-dimensional acoustic axisymmetric duct-cavity structures. We demonstrate numerically tha…
Gate controlled resonant widths in double-bend waveguides: Bound states in the continuum
Almas F. Sadreev, Dmitrii N. Maksimov, Artem S. Pilipchuk
We consider quantum transmission through double-bend - and -shaped waveguides controlled by the finger gate potential. Using the effective non-Hermitian Hamiltonian approach…
Square-Central and Artin-Schreier Elements in Division Algebras
Demba Barry, Adam Chapman
We study the behavior of square-central elements and Artin-Schreier elements in division algebras of exponent 2 and degree a power of 2. We provide chain lemmas for such elements i…
