Abstract
A semi-analytical technique to simulate spatially dispersive (SD)
cylindrical metasurfaces is proposed and demon- strated. This method is
based on the well-known Eigenfunction Expansion (EFE) method and extends
the work of [1], [2] by integrating the Extended GSTCs into this
pre-existing method specific to cylindrical surfaces. This method is
then applied to several cylindrical metasurfaces composed of spatially
dispersive wire dipole unit cells, and successfully verified against
commercial full-wave simulations. Finally, using a case of a closed
metasur- face shell, the usefulness of the proposed EFE-SD method is
shown to illustrate the effect of metasurface thickness on the scattered
fields inside and outside the shell.
