Bound states in the continuum in multilayered time-varying metasurfaces
Puneet Garg, Michael Plum, Carsten Rockstuhl
Time-varying metamaterials involve a rapid temporal modulation of the permittivity, often at frequencies comparable to the oscillation frequency of light. However, pronounced physi…
Spectrum of the Maxwell Equations for a Flat Interface between Non-Homogeneous Dispersive Media in 2D and 3D
Tomáš Dohnal, Michael Plum, Karl M. Schmidt +1
The present work concerns the time-harmonic Maxwell equations in two- and three-dimensional space, divided into two half-spaces by a flat interface. The two half-spaces are filled…
A Two-Stage Finite Element Approach for High-precision Guaranteed Lower Eigenvalue Bounds
Xuefeng Liu, Michael Plum
Obtaining high-precision guaranteed lower eigenvalue bounds remains difficult, even though the standard high-order conforming finite element (FEM) easily yields extremely sharp upp…
Boltzmann's Billiard Systems: Computation of the Billiard Mapping and Some Numerical Results
Michael Plum, Airi Takeuchi, Lei Zhao
L. Boltzmann proposed a billiard model with a planar central force problem reflected against a line not passing through the center. He asserted that such a system is ergodic, which…
Dynamics of the black soliton in a regularized nonlinear Schrodinger equation
Dmitry E. Pelinovsky, Michael Plum
We consider a family of regularized defocusing nonlinear Schrodinger (NLS) equations proposed in the context of the cubic NLS equation with a bounded dispersion relation. The time…
Breathers and rogue waves for semilinear curl-curl wave equations
Michael Plum, Wolfgang Reichel
We consider localized solutions of variants of the semilinear curl-curl wave equation for $(x,t)…
