Abstract
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.
