Research output: Contribution to journalConference articlepeer-review


A general formulation was developed to model the dispersion effect in time-domain finite element method (TDFEM). The TDFEM was based on the second-order vector wave equation and the required convolution integral was evaluated recursively without the requirement to store the fields of all past time steps. The evaluation was ensured of second order in by adopting a linear interpolation for the fields within each time step. A metallic sphere coated with either plasma or a second-order Lorentz medium was considered, and the boundary integral equation was used to truncate the finite element mesh.
