“…The modeling of planar GSTCs was previously reported using the Finite Difference Frequency Domain (FDFD) method [5] and Finite Element Method (FEM) [6]. Other canonical shapes such as cylindrical metasurfaces [7]- [9] and spherical metasurfaces [10], [11] are now being studied. Integral Equation -Method of Moment (IE-MoM) was applied to circular cylindrical metasurfaces in [7].…”

<div>This work validates cylindrical IE-GSTC by applying it to physical metasurfaces, i.e. metasurfaces defined by material properties and dimensions rather than by susceptibility tensor components. Previously reported IE-GSTC which was formulated for zero thickness GSTC discontinuity is extended to handle finite thickness of physical metasurfaces. A simple analytical approach is used to extract the bianisotropic susceptibility tensor of concentric, multilayered, magneto-dielectric shell. Plane wave scattering by a physical metasurface constructed of four segments of multilayered, magneto-dielectric metasurface scatterers is used as an example problem to validate cylindrical IEGSTC. A second example considers an opening on the cylindrical metasurface, confirming IE-GSTC can handle metasurfaces with openings. Good agreement is obtained between IE-GSTC results and full wave simulation results for both cases.</div>

“…Previous works in this approach include the application of Finite Difference Frequency Domain (FDFD) method [8] and Finite Element Method (FEM) [9] to the modeling of planar GSTCs. Even though most of the metasurfaces reported to date are planar, other canonical shapes such as cylindrical metasurfaces [10][11][12][13] and spherical metasurfaces [14,15] are now being studied. Applications of conformal metasurfaces include illusion transformation [13], cloaking [12], high-gain antennas [16] and so on.…”
