A precise target recognition method for short-window SSVEP signals is proposed. This method constructs a signal extension model (DP-MAFD-SEM) using SSVEP signals corresponding to one or more stimulus targets. The short SSVEP signal is extended using this model to increase its length. Then, a canonical correlation analysis (SE-CCA) method based on signal extension is used to identify and classify characteristic frequencies. Extending the short-window SSVEP signal length improves the reliability of covariance matrix estimation methods such as CCA, achieving higher recognition accuracy. This invention provides a novel perspective and approach to improving the recognition accuracy of specific frequencies in short SSVEP signals, achieving higher recognition accuracy with shorter signals. This is beneficial for further improving the information transmission rate of SSVEP-BCIs, promoting the development of high-speed SSVEP-BCIs, and facilitating their practical application.

The application discloses a method for in-situ reduction synthesis of a plasma heterojunction material and application of the plasma heterojunction material in piezoelectric-photocatalytic degradation of dye wastewater. 12 The heterojunction catalyst can realize high-efficiency catalytic conversion through electronic mechanical coupling and solar-induced photogenerated carriers. When the material is applied to MB dye degradation, high piezoelectric-photocatalytic activity is exhibited. Compared with a piezoelectric or photocatalytic method alone, piezoelectric-photocatalysis is a high-efficiency environmental purification technology. In addition, the metal titanium template is first recycled for synthesis of the Bi / BTO catalyst, which is beneficial to commercial-scale application and industrial production.

This invention discloses a dual-polarization angle-selective surface structure for reducing radar sidelobes, comprising an upper structure and a lower structure, with an air gap between them. Both the upper and lower structures include a plurality of frequency-selective surface units arranged in an array. Each frequency-selective surface unit includes a dielectric substrate. A first metal resonant unit structure is disposed on the upper surface of the dielectric substrate, and a second metal resonant unit structure is disposed on the lower surface of the dielectric substrate. The first and second metal resonant unit structures are connected through metal vias on the dielectric substrate. This structure can solve the problem that radar sidelobe blanking technology cannot simultaneously reduce radar sidelobes and avoid introducing redundant additional interference sources.
