Abstract: A novel finite-volume time-domain (FVTD) model for the Maxwellian absorber is presented to aid numerical simulations on unstructured grid. In the present approach all the electromagnetic (EM) field quantities are colocated in both space and time. Theoretical development of the co-located FVTD formulation and a practical application of the Maxwellian absorber as an unsplit perfectly matched layer (PML) for waveguide problems are presented. For variations of the angle of incidence from near normal to 50 degree, the reflection coefficient of the FVTD-Maxwellian absorber is lower than -40 dB.
