第２の実施形態の電磁波反射装置の構成を図４に示す。図４に示した電磁波反射装置２は、図３に示した電磁波反射装置２を、紙面上下方向に繰り返し配置したものである。図４に示した電磁波反射素子２１−１、２１−２、２１−３、２１−４は、図３に示した電磁波反射素子２１−１、２１−２、２１−３、２１−４と比べて、それぞれ、共振線２４−１、２４−２、２４−３、２４−４をさらに備える。   The configuration of the electromagnetic wave reflection device according to the second embodiment is shown in FIG. The electromagnetic wave reflection device 2 shown in FIG. 4 is obtained by repeatedly arranging the electromagnetic wave reflection device 2 shown in FIG. 3 in the vertical direction on the paper surface. The electromagnetic wave reflecting elements 21-1, 21-2, 21-3, and 21-4 shown in FIG. 4 are compared with the electromagnetic wave reflecting elements 21-1, 21-2, 21-3, and 21-4 shown in FIG. Respective resonance lines 24-1, 24-2, 24-3, and 24-4 are further provided.

（変形例）
図２、４においては、電磁波反射素子における反射位相が、互いに直交する偏波間で同様になるように、共振線の長さが、互いに直交する偏波間で同様に設計されている。変形例としては、電磁波反射素子における反射位相が、互いに直交する偏波間で独立になるように、共振線の長さが、互いに直交する偏波間で独立に設計されてもよい。 (Modification)
2 and 4, the lengths of the resonance lines are similarly designed between the polarized waves orthogonal to each other so that the reflection phase in the electromagnetic wave reflecting element is the same between the polarized waves orthogonal to each other. As a modification, the length of the resonance line may be designed independently between the polarized waves orthogonal to each other so that the reflection phase in the electromagnetic wave reflecting element is independent between the polarized waves orthogonal to each other.

図２、４においては、紙面左右方向の共振線が、折り曲げられることにより、紙面左右方向の電磁波反射素子の配置を密にしている。変形例としては、紙面上下方向の共振線が、折り曲げられることにより、紙面上下方向の電磁波反射素子の配置を密にしてもよい。あるいは、紙面左右方向の共振線及び／又は紙面上下方向の共振線が、紙面垂直方向にビア構造により折り曲げられることにより、紙面左右方向の電磁波反射素子の配置及び／又は紙面上下方向の電磁波反射素子の配置を密にしてもよい。   2 and 4, the resonance lines in the left-right direction on the paper surface are bent, so that the electromagnetic wave reflection elements in the left-right direction on the paper surface are densely arranged. As a modification, the resonance lines in the vertical direction of the paper may be bent so that the electromagnetic wave reflecting elements in the vertical direction of the paper are densely arranged. Alternatively, the resonance line in the horizontal direction on the paper surface and / or the resonance line in the vertical direction on the paper surface is bent in the vertical direction on the paper surface by the via structure, thereby arranging the electromagnetic wave reflection elements in the horizontal direction on the paper surface and / or the electromagnetic wave reflection element in the vertical direction on the paper surface. The arrangement may be dense.

図２、４においては、電磁波反射装置を構造物に設置している。変形例としては、既存の平面アンテナ装置において、各アンテナ素子に共振線を接続してもよい。   2 and 4, the electromagnetic wave reflection device is installed in the structure. As a modification, in an existing planar antenna device, a resonance line may be connected to each antenna element.

本発明の電磁波反射装置は、電磁波を面内に垂直な入射方向と異なる一方向に反射させる目的（例えば、レーダ探査回避）で、又は、電磁波を面内に垂直な入射方向と無相関な方向に散乱させる目的（例えば、電波暗室）で、適用することができる。   The electromagnetic wave reflection device of the present invention is for the purpose of reflecting an electromagnetic wave in one direction different from the incident direction perpendicular to the plane (for example, avoiding radar search) or a direction uncorrelated with the incident direction perpendicular to the plane. It can be applied for the purpose of scattering the light (for example, an anechoic chamber).
