摘要:
The present invention is an aperture array structure used in a method of measuring characteristics of a specimen by applying an electromagnetic wave to an aperture array structure on which the specimen is held, and detecting frequency characteristics of the electromagnetic wave scattered by the aperture array structure. The aperture array structure includes a first principal surface, a second principal surface opposed to the first principal surface, and a plurality of apertures extending through the aperture array structure in a direction perpendicular to the first principal surface and the second principal surface. An opening area of each aperture at the first principal surface is smaller than an opening area of each aperture at the second principal surface.

Provided is a perforated-structure body that has high mechanical strength and is not likely to bend or be damaged when being handled. In a perforated-structure body 1, which is used in measurement of a characteristic of a measurement target performed by radiating electromagnetic waves, a plurality of perforations 2c are provided in a perforated plate 2, which has a first main surface 2a and a second main surface 2b that opposes the first main surface 2a, so as to penetrate from the first main surface 2a to the second main surface 2b, and support substrates 3 and 4 are stacked on at least one main surface among the first main surface 2a and the second main surface 2b of the perforated plate 2 so as to have an opening or a cut out portion through which at least one of the perforations 2c is exposed.

According to the present invention, a plate-shaped periodic structure includes at least two aperture portions extending through the periodic structure in a direction perpendicular to a main surface of the periodic structure and periodically arranged in at least one direction along the main surface. Each of the aperture portions has a shape that is not mirror-symmetric with respect to an imaginary plane that is a plane perpendicular to the main surface. Each of the aperture portions includes a constricted portion at which a gap distance of the aperture portion is partially small, the gap distance being a width in a direction parallel to a line of intersection of the main surface and the imaginary plane.
