FREQUENCY SELECTIVE REFLECTOR AND REFLECTIVE STRUCTURE

To provide a reflection structure including a frequency selective reflection plate that can suppress attenuation of electromagnetic waves by a protection member without imposing restrictions on design and whose reflection characteristics can be easily customized.SOLUTION: A reflective structure 20 includes a frequency selective reflector 1 that reflects electromagnetic waves in a direction different from the specular reflection direction, and a protective member 21 placed above the frequency selective reflector 1, and the thickness of the protective member 21 is less than 1/4 of the effective wavelength of the electromagnetic wave propagating within the protective member 21, and the protective member 21 includes an adhesive layer 6 and a protective sheet 22 in order from the frequency selective reflector 1.SELECTED DRAWING: Figure 18 【課題】設計に制約を与えることなく、保護部材による電磁波の減衰を抑制することが可能であり、反射特性をカスタマイズすることが容易な周波数選択反射板を含む反射構造体を提供する。【解決手段】反射構造体２０は、電磁波を正反射方向とは異なる方向に反射する周波数選択反射板１と、周波数選択反射板１の上方に配置された保護部材２１と、を有する反射構造体２０であって、保護部材２１の厚さが、保護部材２１内を伝搬する電磁波の実効波長の１／４未満であり、保護部材２１は、周波数選択反射板１から順に、接着層６と、保護シート２２と、を有する。【選択図】図１８
