The excitation of multiple SPP waves as Floquet harmonics was demonstrated instructures fabricated as one-dimensional photonic crystals (PCs) on top oftwo-dimensional gold gratings. Each period of the PC comprised nine layers ofsilicon oxynitrides of different compositions, and each PC had either two orthree periods. Absorptances for obliquely incident $p$- and $s$-polarized lightwere measured in the 500--1000-nm wavelength regime and the sharp bands in theabsorptance spectra were compared with the solutions of the underlyingcanonical boundary-value problem. The excitation of multiplesurface-plasmon-polariton (SPP) waves as Floquet harmonics was confirmed. Thestructures demonstrated broadband absorption with overall weak dependences onthe incidence angle and the polarization state of the incident light, and haspotential application for harvesting solar energy.
