Abstract

To provide a laminate structure that can obtain electromagnetic wave transmission or blocking performance required for design while using a metal layer as it is without processing it.SOLUTION: A laminate structure 10 is configured such that the intensity of the outgoing wave relative to the incident wave is stronger for electromagnetic waves below a predetermined frequency than for electromagnetic waves above a predetermined frequency, and includes a laminate 1 having at least one plate material 2 and a metal layer 3 laminated on the at least one plate material 2, and a metasurface sheet 4 attached to the laminate 1, and the metasurface sheet 4 is configured such that the intensity of the outgoing wave relative to the incident wave is stronger for electromagnetic waves of the predetermined frequency or higher than for electromagnetic waves of below the predetermined frequency.SELECTED DRAWING: Figure 3
