Abstract: There is provided a laminated soundproof structure formed by laminating a single layer soundproof structure having one or more soundproof cells which are arranged in a two-dimensional plane and each of which includes a frame, a film, and an opening portion including a hole. The single layer soundproof structure has a shielding peak frequency, which is determined by the opening portion of each of the soundproof cells and at which a transmission loss is maximized, on a lower frequency side than a first natural vibration frequency of the film of each of the soundproof cells. The soundproof cells of the single layer soundproof structures are laminated with a distance therebetween, and at least some of the laminated soundproof cells have the same conditions of the frame, the film, and the opening portion.

Abstract: An optical electric field enhancing device is used with a measuring method which includes two-dimensionally scanning a surface in in-plane direction of the surface to detect, from the rear surface side of the device, signal light emitted from each scanning point when excitation light is applied, and obtaining a two-dimensional signal image on the surface based on the detected signal light. The device includes a transparent substrate, a marker pattern directly formed on the transparent substrate and extending in a direction non-parallel to the main scanning direction of the two-dimensional scanning, and fine uneven structures formed on the marker pattern and the transparent substrate where at least the surface is made of a metal film.
