摘要
随着低空经济产业加速发展,低空安防日益引起广泛关注。我们提出了一种片上固态高功率微波新思路,并在单个厚度0.5mm、直径0.15m的半导体晶圆上集成了储能电容、高功率光控半导体开关及天线,实现了辐射因子20kV的超宽谱高功率微波输出。实验表明,基于集成化片上高功率微波系统,对10m处的消费级无人机造成了通信链路切断及飞行失控的效果。
[Background]As the low-altitude economy industry accelerates,low-altitude security has attracted increasing attention.High-power microwave(HPM)is one of the important means to address the security threats posed by non-cooperative unmanned aerial vehicles(UAVs).[Purpose]As a type of high-power electromagnetic pulse,ultra-wideband high-power microwave(UWB-HPM)can attack the electronic information systems of non-cooperative UAVs through“front-door”or“back-door”coupling,resulting in effects such as interference,disruption,damage,and burnout.[Methods]We propose a new concept of on-wafer high-power microwave on wafer(HPM on-wafer),which integrates energy storage capacitors,high-power optically controlled semiconductor switches,and antennas on a single semiconductor wafer with a thickness of 0.5 mm and a diameter of 0.15 m.[Results]The unit of HPM on-wafer achieves an ultra-wideband high-power microwave output with a radiation factor of 20 kV.[Conclusions]Experiments show that based on this integrated HPM on-wafer unit,the communication link of a consumer-grade UAV at a distance of 10 m is cut off and the UAV loses flight control.By arranging and combining the basic units of HPM on wafer,modular expansion can be realized to form ultra-wideband high-power microwave systems of different scales,which can meet the requirement of achieving the intended strike effect on different platforms.
