(a) Theoretical (top) and experimental (bottom) transmission spectra of the proposed hybrid structure. The inset shows the schematic diagram of the CMD and CSR hybrid structure. The angle of CSR θ, the CSR inner radius Rc and width w of CSR are also marked (b) Ez field distribution of multipolar resonance frequencies at 0.329 THz (C1, dipole), 0.382 THz (C2, quadrupole), 0.422 THz (C3, hexapole), 0.458 THz (C4, octupole), 0.477 THz (C5, decapole), and 0.528 THz (M). The resonance (M) comes from the bright LSP mode supported by the single parallel CSR structure.
