  • Abstract
    The inverse problem of reconstructing boundary deformations in a parallel plate waveguide is solved by using a first order perturbation method applied to the dominant TEM-mode. Regularization using the L-curve criterion is applied and investigated. Reconstruction results from using reflection data are presented and influences from higher order propagating and trapped modes are demonstrated.
