Reliable computation of roots in analytical waveguide modeling using an interval-newton approach and algorithmic differentiation

For the modeling and simulation of wave propagation in geometrically simple waveguides such as plates or rods, one may employ the analytical global matrix method. That is, a certain (global) matrix depending on the two parameters wavenumber and frequency is built. Subsequently, one must calculate al...
