Manual composite material and manual composite material antenna

Abstract

The invention relates to a manual composite material and a manual composite material antenna. The manual composite material is divided into a plurality of areas; an electromagnetic wave emits on a first surface of the manual composite material and exits out from a second surface (opposite to the first surface) of the manual composite material; an intersection part of an ith area and the first surface serves as a bottom surface of the ith area; an intersection part of the ith area and the second surface serves as a top surface of the ith area; an included angle between a connection wire (between a radiation source and one point on the bottom surface of the ith area) and a straight line vertical with the manual composite material is set to be theta; the included angle theta only corresponds to a curve surface in the ith area; a set of points with the same included angle theta on the bottom surface of the ith area form a boundary of the curve surface only corresponding to the inclined angle; the refractive indexes of positions on the curve surface only corresponding to the included angle theta are same; a generatrix of the curve surface is an elliptic arc; and the refractive indexes of the areas can be gradually reduced along with the increasing of the included angle theta. The hopping of the refractive index of the manual composite material provided by the invention is designed to be curved, so that refraction, diffraction and reflection effects at the hopping position can be reduced.

Description

technical field [0001] The present invention relates to the field of electromagnetism, and more particularly, to artificial composite materials and artificial composite material antennas. Background technique [0002] In conventional optical devices, a lens can make the spherical wave radiated by a point light source located at the focal point of the lens become a plane wave after being refracted by the lens. At present, the convergence of the lens is realized by the refraction of the spherical shape of the lens, such as figure 1 As shown, the spherical wave emitted by the radiator 30 is converged by the spherical lens 40 and then emitted as a plane wave. In the process of implementing the present invention, the inventor found that the lens antenna has at least the following technical problems: the spherical lens 40 is bulky and heavy, which is not conducive to the use of miniaturization; Realize the directional propagation of the antenna; the electromagnetic wave reflecti...
