Problems solved by technology

Its characteristic is that the invisible space formed by the combination of isosceles triangles with different vertex angles is closed, and the increase of the scale of the invisible space must be realized by increasing the size of isosceles triangles with different vertex angles, which will inevitably increase the manufacturing cost

Abstract

A light-wave cloaking device and an invisible space expansion method, one end of the base is provided with a front V-shaped prism, the other end is provided with a rear V-shaped prism with the same structure as the front V-shaped prism, and the V-shaped opening of the rear V-shaped prism is connected with the front V-shaped prism The V-shaped opening is opposite, and the front V-shaped prism is symmetrical about the vertical plane. Among the prisms, the left triangular prism and the right triangular prism which are vertically symmetrical and have the same structure, the left triangular prism and the right triangular prism bottom are opposite and parallel to each other, the plane where the left triangular prism bottom, the two sides of the left triangular prism are located, the right triangular prism bottom, and the planes where the left triangular prism two sides are located form a The space in is the invisible space a, and by synchronously increasing the distances between the front V-shaped prism, the rear V-shaped prism, the left triangular prism and the right triangular prism, the invisible space a in the cloaking device can be expanded. Move objects into invisible space a to achieve invisibility.

Description

technical field [0001] The invention belongs to the field of optical technology, and in particular relates to a light wave cloaking device and a cloaking space expansion method. Background technique [0002] "Invisibility" has been a dream of mankind for a long time. Through the unremitting efforts of scientists, stealth technology has made progress in different fields. However, the existing stealth technology is mainly in the microwave band. By coating the surface of the aircraft with materials that can absorb radar waves, the aircraft is prevented from being detected by radar, so as to realize the stealth of the aircraft. However, this technology is not true stealth. In the visible light band, the aircraft is still is visible. Japanese scientists have developed a stealth device, which uses a camera installed on the back of the body and uses the cover of the human body as a display to capture the image of the back of the human body and display it on the cover on the front ...
