Electromagnetic energy collection structure integrating surface plasmon coupler and planar semi-Maxwell fisheye lens

The invention discloses an electromagnetic energy collection structure integrating a surface plasmon coupler and a planar semi-Maxwell fisheye lens, comprising a dielectric substrate, a micro-strip line, a half-Maxwell fisheye lens body, and a super surface. The phase of the super surface changes gradually. The semi-Maxwell fisheye lens body is of a surface metal structure, more than one square metal patch is periodically distributed in rows and columns into a semi-circular shape, and the sizes of the square metal patches decrease gradually from the center to the periphery. The super surface is composed of H-shaped structure units periodically distributed in rows and columns, and the sizes of the H-shaped structure units decrease gradually from a side close to the semi-Maxwell fisheye lens to a side away from the semi-Maxwell fisheye lens. Spatial electromagnetic wave can be effectively converted into surface wave and energy can be concentrated, so that efficient energy collection is realized. The electromagn
