Title   the effects of high power microwave on PIN diode limiter  Abstract High Power Microwave(HPM) technique is a new major field which has been developed by the joining of three science areas,the pulsed power, the plasmas physics  and the microwave electronic developments since 1970.The most potential economic and military application for all HPM sources is electromagnetic radiation.HPM weapons have many advantages which can be used in nearly  all weather and traveling at the speed of light, et a1.However, whether HPM systems  would be useful military weapons depended on answers of serial HPM effects questions. In this essay, the works are concentrated on microwave pulse parameters such as power,wave frequency, pulse width affect on whole HPM effects results through experimental studies and electronics mechanism analysis joined closely.The special effects trends are found by experiments and the reasonable physical clarification  might be built by electronic mechanism analysis. First,  The  first  chapter  expounds  the  significance  of  this  topic  research, including the research background, diode limiter development trend, and domestic  and  international  research  trends. Due to the multiple disciplines in HPM effects field, methodology and associated  Theoretical and experimental effects mechanism studies on typical radar from.  ends has been given in Chapter 2 and Chapter 3.The main purpose of these two chapters works are to obtain  some valuable and reasonable effects mechanism explanation and summarizes in  physical layer by simulations and experiments.The Simulation Program  Advanced Design System(ADS)modelsfor PIN limiters were proposed  and simulated.  the  limiter  important physical  properties.  such  as  spike  leakage  of  power,  pulse  width,  mechanism of  the  front  through circuit simulations and injected experiments.It has been discovered that the ADS simulations are powerful in HPM effects researches.
