Artificial medium complex, artificial medium lens and manufacturing method

Abstract

The invention discloses an artificial medium complex, an artificial medium lens and a manufacturing method. Metal layers are located on the front face and the back face of a plate and distributed in a crossed metal wire mode. And foaming materials are adhered to the outer sides of the metal layers. And space formed by the artificial medium lens contour is filled with artificial medium complex. The problem of high manufacturing difficulty of the method in the prior art is solved.

Description

technical field [0001] The present application relates to the field of radio antennas, in particular to an artificial dielectric complex, an artificial dielectric lens and a manufacturing method. Background technique [0002] A Lunberian lens or a Lunberian lens can converge incident electromagnetic waves of a specific wavelength, and similarly, it can also reflect electromagnetic waves back along the original direction. Theoretically, the dielectric constant of the dielectric material used for Lunberg lenses should change continuously from 2 to 1 following certain mathematical laws from the center of the sphere to the outer diameter. However, such an ideal medium does not exist in nature, so in actual design, discrete spherical shells with layered design are often used instead. In the past, many people used the drilling method to control the dielectric constant of the material through the proportion of the material volume occupied by the hole, but this method is not easy t...
