Electromagnetic energy collector based on metasurface

Abstract

The invention discloses an electromagnetic energy collector based on a metasurface. The electromagnetic energy collector comprises an upper metal layer, a lower metal layer, metal through holes and adielectric layer located between the upper metal layer and the lower metal layer. The upper metal layer comprises four identical U-shaped groove square patches, and the four identical U-shaped groovesquare patches are rotationally symmetrical; a circular hole is formed in the lower metal layer, and the position of the circular hole coincides with the central position of the U-shaped groove squarepatches; each metal through hole is formed in the geometric center of one U-shaped groove square patch, penetrates through the dielectric layer and is perpendicular to the lower metal layer; and a resistor is connected between the bottom end of the metal through hole and the lower metal layer. The electromagnetic energy collector has very good energy absorption capability, unclear polarization and angle stability at 5.8 GHz, and can be used for microwave energy transmission and collection of environmental electromagnetic waves in a complex electronic environment.
