Research output: Contribution to journalConference articlepeer-review


A new waveguide port algorithm for transient finite element method (FEM) computations is introduced. The waveguide port algorithm is suitable for homogeneous waveguides of arbitrary cross section as well as similar problems in e.g. acoustics. This paper demonstrates the new waveguide port algorithm by using it in conjunction with the stable FEM-FDTD hybrid for the computation of the scattering parameter of a patch antenna fed by a coaxial cable.
