Mortar Thin Shell Approximation for Analysis of Superconducting Accelerator Magnets
Robert Hahn, Erik Schnaubelt, Mariusz Wozniak +2
Thin layers can lead to unfavorable meshes in a finite element (FE) analysis. Thin shell approximations (TSAs) avoid this issue by removing the need for a mesh of the thin layer wh…

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…
