Abstract :
We propose an efficient eigenmode solver for electromagnetic cavities based on the Jacobi-Davidson (JD) method and hierarchical finite elements (FE) of high order. The JD algorithm enables us to exploit the multilevel structure of the FE space at various stages of the solution process. As a result, the computational complexity of the suggested method is very low, which is particularly useful for large-scale projects
