Have you tried the Non-parametric Optimization in CST Studio Suite yet? In the newly released version 2026, the workflow is well streamlined with complete integration of the Tosca technology and all results available in a single environment.
Further highlights include the extension of manufacturing constraints, as well as a preview feature for the shape/topology reconstruction – enabling further optimization and modelling!
Here is a demonstration of a Septum Polarizer that achieves an axial ratio of better than 0.3 dB over a 17 % bandwidth after shape optimization.
If you have a S2X license you can try it out today. Simply refer to the Component Library for a few examples.
