InactiveCN103259097Asimple designeffective technical approach
The invention discloses a terahertz metamaterial unit structure and a preparation, adjusting and control method thereof and relates to the technical field of metamaterials and terahertz detection. The terahertz metamaterial unit structure is composed of a bottom layer, a middle medium layer and a surface layer, wherein the bottom layer is a layer of continuous metal film, the middle medium layer is one of a polyimide film, a silicon nitride film, a silicon oxide film, an amorphous silicon film, a silicon oxynitride film, an aluminum oxide film, a hafnium oxide film and an aluminum and hafnium oxide film, and the surface layer is a surface resonator, and the surface resonator is graphical metal with the interior in an H shape and the periphery of a framework structure. According to the adjusting and control method of the terahertz response characteristic of the metamaterial, the whole metamaterial unit structure meeting impedance matching requirements can be decreased or amplified proportionally, and the terahertz absorption frequency and the response frequency band of the metamaterial can be adjusted within an ideal range. The terahertz metamaterial unit structure has the advantages of being simple in structure, easy to integrate, and capable of being applied to terahertz detectors.

Geological record acquisition system, and management and control method based on network and android system

ActiveCN104850945Asimple designVersatile
The present invention discloses a geological record acquisition system, and a management and control method based on the network and an android system, which comprises an engineering management module, a project planning module, a data collection module, a data analysis module and a background maintenance module. The practical application of the system shows that, engineering actual requirements can be met. Not only the content of geological survey records at a geotechnical engineering site is specified, but also the varying problem from person to person can be effectively solved. Meanwhile, during the recording process, the information, such as GPS coordinates, time and the like, can be automatically collected, so that two traceable means, namely the time means and the space means, are provided for the quality control at the geotechnical engineering site. The fresh first-hand information is provided for the proofreading and reviewing operation by photographing and video-shooting modules. The collection and transmission of electronic data greatly improves the working efficiency and effectively reduces the occurrence of human errors during the data transmission process. The accurate transmission of the first-hand survey information is ensured. Therefore, the system and the method have tremendous application potential in the quality management and control field of geotechnical engineering investigation.

UV-LIGA (Ultraviolet-Lithografie, Galvanoformung, Abformung) method for manufacturing multi layers of mini-type inductance coils on silicon substrate

InactiveCN102723259ASimple designShorten the preparation period
The invention discloses a UV-LIGA (Ultraviolet-Lithografie, Galvanoformung, Abformung) method for manufacturing multi layers of mini-type inductance coils on a silicon substrate. The UV-LIGA method integrates an MEMS (Micro Electro Mechanical System), a micro inductance coil of which the cross section diameter is ten micrometers and even several micrometers can be manufactured through a UV-LAIG craft of photoetching, developing, sputtering and electroforming craft and a PECVD (Plasma Enhanced Chemical Vapor Deposition) technology, and the size limit of the traditional manufacturing method of an inductance coil is broken. The UV-LIGA method disclosed by the invention is used for manufacturing a single-layer mini-type coil or multi layers of series-and-parallel communication structure coils, and the filling of insulation layers between the multi layers of the coils can be carried out through the PECVD technology. The bottom layer insulation effect is good as a silicon wafer is used as a substrate, the silicon wafer is light and the thin, and the operation is flexible; and a chromium plate is used as a masking tool, thus the transshipment from a design configuration to a manufacturing shape can be realized, the design for the size, the shape and the distribution of the inductance coil can be very flexible and simple, multiple sets of the inductance coils can be processed at one step according to the distribution of a masking configuration, the performance cost is high, and the processing efficiency and the forming rate are greatly increased.
