Title: Narrow-band filter based on dielectric metasurface structure and manufacturing method therefor
Inventor: XIA JINSONG
IPC: G02B5/26
Filed: 2018-11-09
Abstract: A narrow-band filter based on a dielectric metasurface structure and a manufacturing method therefor. The narrow-band filter comprises a substrate (3), a multilayer dielectric film (2), and a dielectric metasurface (1) prepared on the film. The dielectric metasurface (1) is of a sub-wavelength periodic structure; a vertically incident beam can excite clustered coherent oscillation of an internal light field of the dielectric metasurface (1), and said oscillation interacts with incident light to change the transmission and reflection characteristics of the light. By designing structural units and arrangement of the dielectric metasurface, the bandwidth of resonance can be reduced, thereby achieving the characteristics of narrow-band filtering. The manufacturing method comprises: forming an anti-corrosion mask of a metasurface pattern structure after growing a multilayer dielectric film material on a substrate; transferring the pattern structure onto a top-layer dielectric film; and removing the mask and cleaning. The manufacturing steps of the narrow-band filter are simple and compatible with CMOS processes, and can simultaneously achieve narrow bandwidth and high extinction ratio. Compared with conventional narrow-band filters having multilayer films, process costs are reduced, and narrower bandwidth and higher reflectivity are achieved.

Abstract: A charging gun having excellent heat conduction and dissipation performance, comprising a gun body (1), terminals (2), insulated sleeves (3), and a metal heat dissipation member (4); rear end portions of the terminals (2) pass through the sleeves (3), the metal heat dissipation member (4) is opened with mounting holes for inserting and fixing the sleeves (3), and the metal heat dissipation member (4) is fixed to the gun body (1). Compared with the existing technology, the present solution prevents short circuiting by using the metal heat dissipation member (4) as a body for fixing the terminals (2) and by using the insulated sleeves (3) to separate the metal heat dissipation member (4) from the terminals (2). Large ceramic members that conventionally fix terminals are removed, thus preventing the difficulty wherein a ceramic member having a large volume tends to break when a hole is opened thereon. Processes for processing the sleeves (3) and opening the mounting holes on the metal heat dissipation member (4) are all convenient, having a low level of machining difficulty. More importantly, metals have good heat dissipation performance, thus by using the metal heat dissipation member (4) as a body for fixing the terminals (2), the heat dissipation performance thereof is greatly improved and the high heat dissipation requirements of a charging gun may be met.
