Abstract

We present recent novel approaches for engineering the dispersion characteristics of guided wave structures. These approaches are highly efficient and depend mainly on the exploited numerical method for calculating the modal parameters. Using these approaches, the modal parameters and their sensitivities with respect to all the design parameters can be obtained efficiently. The computational cost is much less than that for estimating the sensitivities of these parameters using finite difference scheme. The former approach requires many additional simulations proportional to the number of design parameters. Our approaches, however, need no additional simulation for obtaining the sensitivity information. They require the construction of an adjoint problem whose solution is readily available using the original simulation.
