Recovery of periodicities hidden in heavy-tailed noise

Illya M. Karabash, Jürgen Prestin

We address a parametric joint detection-estimation problem for discrete signals of the form $x (t) = \sum_{n = 1}^{N} α_{n} e^{- i λ_{n} t} + ε_{t}$ , $t \in N$ , with an additive no…

Nonlinear bang-bang eigenproblems and optimization of resonances in layered cavities

Illya M. Karabash, Olga M. Logachova, Ievgen V. Verbytskyi

Quasi-normal-eigenvalue optimization is studied under constraints $b_{1} (x) \leq B (x) \leq b_{2} (x)$ on structure functions $B$ of 2-side open optical or mechanical resonators. We prove…
