A Mixed Tree-Cotree Gauge for the Reduced Basis Approximation of Maxwell's Eigenvalue Problem
Anna Ziegler, Sebastian Schöps
Model order reduction methods are a powerful tool to drastically reduce the computational effort of problems which need to be evaluated repeatedly, i.e., when computing the same sy…
Gradient-Based Eigenvalue Optimization for Electromagnetic Cavities with Built-in Mode Matching
Anna Ziegler, Robert Hahn, Victoria Isensee +2
Shape optimization with respect to eigenvalues of a cavity plays an important role in the design of new resonators or in the optimization of existing ones. In our paper, we propose…
Reduced Basis Approximation for Maxwell's Eigenvalue Problem and Parameter-Dependent Domains
Max Kappesser, Anna Ziegler, Sebastian Schöps
In many high-frequency simulation workflows, eigenvalue tracking along a parameter variation is necessary. This can become computationally prohibitive when repeated time-consuming…
On the computation of analytic sensitivities of eigenpairs in isogeometric analysis
Anna Ziegler, Melina Merkel, Peter Gangl +1
The eigenmodes of resonating structures, e.g., electromagnetic cavities, are sensitive to deformations of their shape. In order to compute the sensitivities of the eigenpair with r…
Mode Recognition by Shape Morphing for Maxwell's Eigenvalue Problem
Anna Ziegler, Niklas Georg, Wolfgang Ackermann +1
In electrical engineering, for example during the design of superconducting radio-frequency cavities, eigenmodes must be identified based on their field patterns. This allows to un…
