摘要	We design a periodic Au patch-shaped microstructure covering on an Si substrate. This microstructure exhibits a designable near-infrared narrowband absorption from 1100 to 1500 nm. We investigate its absorption mechanism by the metal-insulator-metal waveguide theory and find that the combination of the plasmonic effect and cavity effect contributes an efficient absorption by calculating the electric field distribution numerically. We further analyze the relationship between the absorption spectra and electric field distributions of the structure with different patch lengths, by which we clarify why the narrowband absorption peak can be linearly shifted by varying the length of the Au patch.
