Infrared absorption enhancement on non-metal nanostructures were studied in this research. The fabrication method of a large area line & space structure of silicon was developed by using the electron beam lithography technique. The line & space nanostrucure of silicon was used for infrared absorption measurements.The theoretical enhancement factor of the infrared absorption was estimated by the regorous coupled-wave analysis (RCWA) method. Although the factor of enhancement of infrared absorption is inferior to that of conventional metal nanostructures, it was suggested that the enhancement of infrared absorption occurs even in nanostructures other than metals. This result opens the way to using SEIRA also in research areas where the application of it was limited by the existence of metal so far.
