Eigenfrequency analysis is an integral part of the numerical modeling toolkit. The eigenmodes of a linear system often have distinct qualitative characteristics and evolve differently over a parameter range, such as frequency. We are often asked if there is a way to keep track of and categorize these families of eigenmode solutions over the parameter sweep. In this blog post, we will demonstrate how to do so using the mode overlap integral in the COMSOL Multiphysics® software. Read more
