Abstract
An electromagnetic scattering film, and an electronic device with the electromagnetic scattering film are provided. The electromagnetic scattering film includes a metal layer, wherein the metal layer is provided with a through hole penetrating through an upper surface and a lower surface of the metal layer, and a maximum value of the distance s between any two points on a contour of a section of the through hole is less than the wavelength λ of a microwave emitted into the through hole, such that the microwave is diffracted after being emitted into the through hole. By arranging, on the metal layer, a through hole being smaller than the wavelength of a microwave, the microwave, which was originally transmitted in a linear manner, is diffracted after being emitted into the through hole, thereby expanding a microwave transmission and/or receiving space range.
