<P>PROBLEM TO BE SOLVED: To provide a reflective structure allowing a variable width of a reflection phase at a medium boundary to be set at 360 degrees or more. <P>SOLUTION: A reflective structure includes a planar ground conductor plate 11; a dielectric layer 12 disposed on the ground conductor plate 11; and a plurality of small metal plates 13 and a plurality of metal bodies 14 disposed on the dielectric layer 12. A length of the dielectric layer 12 in a direction perpendicular to the ground conductor plate is approximately 0.5 times a wavelength in an operation frequency. The small metal plates 13 are arranged substantially periodically on a surface of the dielectric layer 12 on a plane opposite the ground conductor plate 11. The metal bodies 14 are respectively a polyhedron whose one side length is smaller than approximately 0.5 times the wavelength in the operation frequency, and are respectively disposed between the ground conductor plate 11 in the dielectric layer 12 and each of the small metal plates 13. <P>COPYRIGHT: (C)2013,JPO&INPIT |
