Abstract

The invention relates to an electromagnetic scattering film which comprises a conducting layer. A plurality of grooves are formed in the first surface of the conducting layer at intervals, the inner wall of each groove is spherical, at least one first through hole is formed in the inner wall of each groove, and the other end of each first through hole penetrates through a second surface opposite to the first surface. The maximum value of the distance S between any two points on the profile of the cross section of the first through hole is smaller than the wavelength lambda of the electromagnetic wave incident to the first through hole. According to the electromagnetic scattering film, the spherical groove is formed in the first surface, and the first through hole communicated with the groove is formed in the second surface, so that electromagnetic waves are diffracted and reflected when penetrating through the electromagnetic scattering film, the propagation direction of the electromagnetic waves is diverged, and the propagation range is expanded.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an electromagnetic scattering film. Background technique [0002] In radio communication, because the electromagnetic wave has the physical characteristic of linear propagation, it is necessary to place the receiving device in the direction of propagation of the electromagnetic wave, so the installation position of the device is limited. [0003] Therefore, there is an urgent need for an electromagnetic scattering film, which can change the propagation direction of electromagnetic waves during propagation and expand the propagation range. Contents of the invention [0004] The purpose of the present invention is to provide an electromagnetic scattering film, which can make the electromagnetic wave diffract and reflect when passing through the first through hole and the groove, diverge the propagation direction of the electromagnetic wave, and expand the propagation range....
