The current distributions on the metasurface (left column) and metallic ground sheet (right column) under y-polarized wave incidence when r₃ = 1.4 mm at (a) 12.5 GHz, (b) 14.0 GHz, (c) 19.8 GHz, and when r₃ = 1.5 mm at (d) 13.0 GHz, (e) 19.2 GHz. The red arrow indicates the equivalent current direction.
