Techniques for electromagnetic modelling of EM structures are described. Krylov subspace of a second EM structure (104, 504) is augmented with Eigen vectors of a first EM structure (102, 502) to form an augmented space. The second EM structure (104, 504) is a design variant of the first EM structure (102, 502) and the first EM structure (102, 502) is already EM modelled and simulated. Thereafter, Maxwell's equations for the second EM structure (104, 504) are solved using the augmented space. |
