a THz wave absorption of periodic split-ring structures with different opening widths (s). The split-rings have an outer radius of 15 μm, an inner radius of 10 μm and a thickness of 10 nm. b THz wave absorption of periodic split-ring structures with different ring widths (d). The split-rings have an outer radius of 15 μm, an opening width of 2 μm and a thickness of 10 nm
