Problems solved by technology

[0003] However, the glass curtain wall also brings many disadvantages. For example, when the outdoor sunlight is too hot, it is necessary to use curtains to block the sunlight; The reflection of the mirror surface produces strong and dazzling reflection glare
Strong reflected glare causes light pollution, which greatly increases the chance of accidental traffic accidents
When the reflected glare enters a high-speed car, it will instantly stimulate the driver's sight, causing sudden temporary blindness and visual illusion, causing serious harm to both pedestrians and drivers

Embodiment Construction

[0025] Light, as a type of electromagnetic wave, when passing through glass, because the wavelength of light is much larger than the size of atoms, we can use the overall parameters of the glass, such as the refractive index, rather than the detailed parameters of the atoms that make up the glass to describe The response of glass to light. Correspondingly, when studying the response of materials to visible light or other electromagnetic waves, the response of any structure with a scale much smaller than the wavelength of electromagnetic waves to electromagnetic waves can also use the overall parameters of the material, such as permittivity ε, permeability μ, refractive index , impedance, etc. By designing the structure of each point of the material, the permittivity and permeability of each point of the material are the same or different, so that the overall permittivity and permeability of the material are arranged regularly, and the regularly arranged permeability and permea...

Abstract

The invention discloses a glass curtain wall, which is formed by overlapping a plurality of metamaterial sheet layers, wherein each metamaterial sheet layer comprises a substrate and artificial metal micro-structures which are periodically arrayed on the substrate; the glass curtain wall has equal relative dielectric constant and relative permeability when being passed by visible light; and the visible light passes through the glass curtain wall in a no-reflection and no-loss manner. The glass curtain wall is prepared by using a metamaterial principle to get rid of various defects caused by self physical properties of the conventional glass curtain wall, such as serious reflection phenomenon, bad transmission phenomenon and the like. According to the glass curtain wall, the artificial metal micro-structures are periodically arrayed on the substrate so that the visible light can completely pass through the glass curtain wall and is not reflected; and therefore, the light pollution problem of the conventional glass curtain wall is avoided.

Description

technical field [0001] The invention relates to the field of optical devices, in particular to a glass curtain wall. Background technique [0002] Glass curtain wall is a beautiful and novel architectural wall decoration method, which is a distinctive feature of the era of modernist high-rise buildings. It makes the building present different tones from different angles, giving people a dynamic beauty with the changes of sunlight, moonlight and lighting. [0003] However, the glass curtain wall also brings many disadvantages. For example, when the outdoor sunlight is too hot, curtains need to be used to block the sun; The reflection of the mirror surface produces a strong and harsh reflection glare. Strong reflection glare causes light pollution, which greatly increases the probability of accidental traffic accidents. When the reflected glare enters a high-speed car, it will instantly stimulate the driver's sight, causing sudden temporary blindness and visual illusion, ca...
