Abstract
The characterization of microwave devices by means of the FDTD method is highly dependent on the availability of suitable absorbing boundary conditions. This letter presents absorbing boundary conditions that a re particularly appropriate for the analysis of waveguide devices beca use both propagating and evanescent modes are absorbed. Additionally, the modal decomposition of the total field provided by FDTD is shown t o constitute an alternative procedure to frequency domain methods in t he wideband multimode characterization of microwave devices.
