This invention discloses a high-power pulsed radiation source based on low-dimensional nanomaterials, belonging to the field of pulsed radiation sources. It includes an integrated base, a lamp head, and internal core functional units. The lamp head has an emission window, a fan-shaped lamp cover, and a cleaning rod. Through an operating ring linked to a gear ring, gears, and a worm gear structure, the opening and closing of the lamp cover and the cleaning of the window can be achieved synchronously. The sealed emission window can isolate dust and moisture. The power supply unit, pulse drive unit, low-dimensional nanomaterial emission module, and radiation control unit within the integrated base work collaboratively. The power supply unit provides dual-path power, the pulse drive unit transmits excitation signals and receives feedback, the emission module generates pulsed radiation, and the control unit achieves timing matching through a synchronization signal. This invention is easy to operate and maintain, ensuring both the cleanliness of the emission window and the safety of internal components, while also improving the stability and power of the pulsed radiation output, solving the problems of cumbersome maintenance and insufficient coordination in existing technologies.

This disclosure provides an intelligent system and its antenna gain enhancement device. The antenna gain enhancement device includes several metal components and an insulating housing. Each metal component comprises an insulating main body and a metal layer and an insulating layer sequentially arranged from the inside out on the outer surface of the main body. Several independent metal components are arranged within the housing in a predetermined manner. The antenna gain enhancement device is matched with the antenna in the intelligent system. The metal components are used to generate polarization under the influence of an applied electromagnetic field to improve antenna gain. In this disclosure, by designing the antenna gain enhancement device to include several metal components and an insulating housing, these metal components do not require assembly and are directly installed into the housing in an ordered or disordered manner. This achieves polarization under the influence of an applied electromagnetic field, forming an enhanced electric field in the direction of electromagnetic wave propagation, thereby enhancing antenna gain and enabling wider communication range, smoother network speeds, and lower signal latency.
