针对传统传输式电磁脉冲（EMP）模拟器存在测试空间受限的问题，提出一种基于线栅卷边结构的横电磁波（TEM）天线的定向辐射式快沿电磁脉冲（FREMP）模拟器设计方案。通过数值仿真，研究线栅卷边TEM喇叭天线结构参数和吸收电阻对辐射场的影响，仿真结果表明卷边TEM喇叭天线可以有效提高低频辐射能力，可为研制定向辐射式快沿电磁脉冲模拟器提供理论支撑。另通过实验，验证利用线栅卷边结构TEM喇叭天线研制辐射式快沿电磁脉冲辐射波模拟器的可行性。结果表明：利用线栅卷边结构TEM喇叭天线研制的定向辐射式快沿电磁脉冲模拟器的辐射场可达到高空核电磁脉冲（HEMP）标准的要求。

In order to solve the problem that the traditional transmission mode electromagnetic pulse (EMP) simulator is relative smaller,a new method to generate EMP radiation field is presented in this paper based on a wire edge curled TEM horn antenna. The influences of the parameters of the antenna and the re?sistance absorption to the radiation field are analyzed through numerical simulation. The results show that edge curled TEM horn antenna can enhance the radiation capability significantly in the low frequency band,and can provide theoretical references for the design of directional fast risetime electromagnetic pulse(FREMP)radiating-wave simulators. The feasible of design FREMP radiating-wave simulator is val?idated using wire edge curled TEM horn antenna through experiment. The measurement results show that the radiation waveform radiated by the wire edge curled TEM horn antenna successfully meets the require?ment of the HEMP in military standards.
