Analysis of the research development on HPM/EMP protection

High power microwave(HPM)and electromagnetic pulse(EMP)weapons both are highly lethalweapons in modern warfare. In order to protect modern weaponry against HPM/EMP attack,frontier tech-nologies and methods such as adaptive electromagnetic protection,microwave reinforcement,and evolv-able hardware are reviewed in this paper,where conventional protection methods are first described basedon the development process of HPM/EMP weaponry and the protection research. Research achievementssuch as radio frequency electromagnetic protection units,picosecond EMP suppression device,and fre-quency selective surface are summarized,with new protection materials being presented in the end. Also,suggestions are given for the future development direction of HPM/EMP protection technology from the per-spective of systematic protection,potential loss of effectiveness of equipment,as well as the standard onHPM/EMP protection.
