| Summary: | We present a multifilament current method (MFCM) incorporated with generalized sheet transition condition (GSTC) to simulate 2.5-dimensional cylindrical metasurfaces with arbitrary cross sections for the first time. The chain-type form of GSTC is synthesized and utilized to relate the tangential fields on two sides of a cylindrical metasurface. The MFCM is subsequently introduced and formulated by deploying the GSTC. The doublet-current unit which contains both electric and magnetic line sources with phase terms is deployed in the MFCM for simulating co- and cross-polarized scattered and transmitted fields from GSTC characterized cylindrical metasurfaces. Three illustrative examples regarding different geometries, different metasurface characteristics and different excitations are presented to validate the proposed simulation technique. In comparison to existing numerical methods, the proposed technique has its merits on simplicity and conciseness. |
