A Domain Derivative for Electromagnetic Scattering by Perfect Conductors in the Time Domain
Marvin Knöller
A domain derivative for time-dependent electromagnetic scattering from perfect conductors is established. By proceeding through the Laplace domain, frequency-dependent bounds on so…

Domain derivative and shape reconstruction for an inverse backscattering problem for the wave equation
Roland Griesmaier, Marvin Knöller, Eliane Kummer
We consider an inverse backscattering problem for time-dependent acoustic waves with a compactly supported penetrable scattering obstacle in unbounded three-dimensional free space.…
