Experimental excitation of multiple surface-plasmon-polariton waves with 2D gratings
Experimental excitation of multiple surface-plasmon-polariton waves with 2D gratings
The excitation of multiple SPP waves as Floquet harmonics was demonstrated in structures fabricated as one-dimensional photonic crystals (PCs) on top of two-dimensional gold gratings. Each period of the PC comprised nine layers of silicon oxynitrides of different compositions, and each PC had either two or three periods. Absorptances for …
