Abstract

Conventional metamaterials for controlling the reflection path of electromagnetic waves have limitations, such as inevitability of thickness variation according to the frequency of the incident wave, electrical instability, and dependence on the designer. In this study, we propose a dielectric structure to control the reflection path of microwaves while overcoming those limitations. The proposed structure prevents reflected waves from returning to the wave source by scattering the incident waves. It is effective in broadband frequency without changing thickness, and electrically stable because it is composed of a dielectric material. A systematic approach called the phase field design method was employed as a design methodology to reduce the dependence on the designer. A three-dimensional (3-D) shaped prototype was fabricated using a 3-D printer, and numerical results were verified through experiments.
