Recent Advances in Mesh Morphing-Embedded Space Mapping Optimization

Space mapping (SM) is widely used in electromagnetic (EM) optimization due to its fast characteristics. For waveguide devices, mesh morphing-embedded space mapping helps speed up electromagnetic optimization of coarse model. In this paper, the recent advances in mesh morphing-embedded space mapping is reviewed from the aspects of parallel SM and coarse- and fine-mesh SM based on mesh deformation. The current mesh morphing technology is not limited to waveguides with rectangular structures, but also waveguides with arc structures can be meshed better with mesh morphing. Two microwave instances of different structures will serve as proof of the aforementioned techniques.
