PROBLEM TO BE SOLVED: To provide a technique for constructing an electromagnetic wave conversion plate in a single layer.SOLUTION: In an electromagnetic wave conversion plate, a unit periodic structure so that a plurality of unit cells including conductive structures that are formed by a conductive material enveloped in a regular square in which a wavelength of an incident electromagnetic wave is a length of one side, and have the similar size is one-dimensionally arranged while changing a value of a structure parameter in regards to a form of the conductive structure in each unit cell is two -dimensionally arranged. A penetration electromagnetic wave is discharged while controlling so that a refractive angle of the penetration electromagnetic wave of the electromagnetic wave entered into the electromagnetic wave conversion plate is different from the refractive angle calculated on the basis of a mean refractive index of the electromagnetic wave conversion plate.SELECTED DRAWING: Figure 1 【課題】電磁波変換プレートを単層で構成する技術を提供すること。【解決手段】入射電磁波の波長を一辺の長さとする正方形に内包される導体物質で形成された同じ大きさの導体構造を非導電性物質の基板のおもて面と裏面にのみ有する単位セルが、前記導体構造が有する形状に関する構造パラメータの値が単位セルごとに変化されて１次元的に複数個配置されている単位周期構造を、２次元的に複数個配置した電磁波変換プレートであって、前記電磁波変換プレートに入射された電磁波の透過電磁波の屈折角が電磁波変換プレートの平均屈折率に基づいて算出される屈折角とは異なるように、前記透過電磁波が制御されて放射される、電磁波変換プレート。【選択図】図１
