Sensitivity analysis of waveguide eigenvalue problems

[摘要] We analyze the sensitivity of dielectric waveguides with respect to designparameters such as permittivity values or simple geometric dependencies.Based on a discretization using the Finite Integration Technique theeigenvalue problem for the wave number is shown to be non-Hermitian withpossibly complex solutions even in the lossless case. Nevertheless, thesensitivity can be obtained with negligible numerical effort. Numericalexamples demonstrate the validity of the approach.
