A circuit based time-domain modelling of Huygens' metasurfaces is proposed and demonstrated using numerical examples. The model is based on Generalized Sheet Transition Conditions (GSTCs) and multi-Lorentz surface susceptibilities describing the metasurface. Using an LCR band-pass filter circuit, the surface susceptibilities are modelled for a general unmatched and lossy metasurface, allowing for both time and frequency domain computation of scattered fields capturing the corresponding dispersive effects.
