| Outline of Final Research Achievements |
In this study, the reflection/transmission controlling device using artificially designed materials are proposed. As the artificially designed material, dipole array sheets and wire grids are used here. Laminated structures consisting of the metal wire array sheets and dielectric material are proposed. Reflection and transmission characteristics of these structures can be controlled by changing the metal wire parameters such as spacing gaps between the wires, and the dielectric material’s thickness and relative permittivity. The reflection and transmission characteristics of the laminated structures are evaluated by measurements in free space and by transmission line theory.
Recently, the technologies using millimeter wave frequencies, for example, automotive radar, high-speed wireless LAN, have been developed. In order to evaluate the shielding effectiveness of materials at millimeter wave range, the free space transmission coefficients measurement setup is newly developed.
