Optimal Design of Tubular Perfectly Conducting Objects in Electromagnetic Chirality
Tilo Arens, Roland Griesmaier, Marvin Knöller +1
This work is about the shape optimization of long tubular objects in electromagnetic chirality (em-chirality). Em-chirality is a property of individual scattering objects or metama…

Localizing acoustic and electromagnetic waves in space and time
Roland Griesmaier, Soumen Senapati
We study time-dependent acoustic and electromagnetic waves governed by the scalar wave equation or Maxwell's equations in a bounded three-dimensional domain. We establish the exist…

Monotonicity-based regularization of inverse medium scattering for shape reconstruction
Roland Griesmaier, Bastian Harrach, Jianli Xiang
We consider the scattering of time-harmonic plane waves by a compactly supported inhomogeneous scattering obstacle governed by the Helmholtz equation. Given far field observations…
