Engineering of the extremely high Q factor in two subwavelength dielectric resonators
E. N. Bulgakov, K. N. Pichugin, A. F. Sadreev
The high-Q {\it subwavelength} resonances in an isolated dielectric disk modes can be achieved by avoided crossing (anticrossing) of the nonorthogonal TE resonances under variation…
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…
Multiple bound states in scissor-shaped waveguides
Evgeny N. Bulgakov, Pavel Exner, Konstantin N. Pichugin +1
We study bound states of the two-dimensional Helmholtz equations with Dirichlet boundary conditions in an open geometry given by two straight leads of the same width which cross at…
Distribution of nearest distances between nodal points for the Berry function in two dimensions
Alexander I. Saichev, Karl-Fredrik Berggren, Almas F. Sadreev
According to Berry a wave-chaotic state may be viewed as a superposition of monochromatic plane waves with random phases and amplitudes. Here we consider the distribution of nodal…
Simulations of interference effects in gated two-dimensional ballistic electron systems
A. P. Jauho, K. N. Pichugin, A. F. Sadreev
We present detailed simulations addressing recent electronic interference experiments, where a metallic gate is used to locally modify the Fermi wave-length of the charge carriers.…
