Finite-Element Eigenvalue Analysis of Propagating and Evanescent Modes in 3-D Periodic Structures Using Model-Order Reduction

Eigenvalue analysis of a periodic structure by the finite-element method gives its Floquet propagation constant at a given frequency. Using this method directly to find the dispersion curve is computationally expensive, particularly in 3-D, because a large matrix eigenproblem must be solved at each...
