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 paperbased 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 thatedge curled TEM horn antenna can enhance the radiation capability significantly in the low frequencyband,and can provide theoretical references for the design of directional fast risetime electromagneticpulse(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 thatthe radiation waveform radiated by the wire edge curled TEM horn antenna successfully meets the require-ment of the HEMP in military standards.
