Field Scattering Analysis of Cylindrical Spatially Dispersive Metasurfaces

In this letter, a semianalytical technique to simulate spatially dispersive (SD) cylindrical metasurfaces is proposed and demonstrated. This method is based on the well-known eigenfunction expansion (EFE) method and extends the works of Smy et al. (2023) by integrating the extended generalized sheet transition conditions into this preexisting method specific to cylindrical surfaces. This method is then applied to several cylindrical metasurfaces composed of SD wire dipole unit cells, and successfully verified against commercial full-wave simulations. Finally, using a case of a closed metasurface 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.
