[IEEE 2018 IEEE International Conference on Computational Electromagnetics (ICCEM) - Chengdu, China (2018.3.26-2018.3.28)] 2018 IEEE International Conference on Computational Electromagnetics (ICCEM) - Analysis of TEM Horn with Dielectric Loaded

摘要： The radiation fields of transverse electromagnetic (TEM) horn as a nuclear electromagnetic pulse(NEMP) radiating-wave simulator are simulated by finite-difference time-domain(FDTD) method. The EMP’s effects of different dielectric load are numerical studied and analyzed. The results show that comparing with the traditional TEM horn antenna the peak value of Ez increases or decreases, but the FWHM never widen as TEM horn loaded by dielectric.
