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 $b_1(x)\le B(x)\le b_2(x)$ on structure functions $B$ of 2-side open optical or mechanical resonators. We prove…
