Title:
輻射デバイスおよび放射冷却装置
Document Type and Number:
Japanese Patent JP7034294
Kind Code:
B2
Abstract:
A radiation device or the like has a structure for selectively converting thermal energy into an electromagnetic wave. The radiation device has a conductor layer, a semiconductor layer, and a plurality of conductor disks. The plurality of conductor disks are arranged on the semiconductor layer so that the same arrangement pattern is constituted in each of a plurality of unit constituent regions each having a rectangular shape with a side of 4.5 to 5.5 μm. The arrangement pattern of individual unit components includes nine conductor disks so as to correspond to a 3×3 matrix, and the nine conductor disks include four or more kinds of conductor disks having diameters different from each other. As a result, a two-dimensional periodic structure of the arrangement pattern is formed on the semiconductor layer.
