Abstract
This paper proposes an extended scheme for the extraction of scattering parameters for the Finite-Volume Time-Domain (FVTD) method. The flux-splitting algorithm that is inherent to the FVTD method is exploited to compute the incident and reflected fields in a port. A novel correction scheme for the magnetic field is applied that yields accurate results of the scattering parameters in non-TEM structures by performing an artificial flux separation. Multimode S-parameters of a waveguide discontinuity, that are determined using the proposed approach, are successfully validated with a Mode-Matching analysis.
