Frequency response of switched high power mesoband electromagnetic pulse generator
摘要
Abstract
The switched λ/4 coaxial oscillator is used to generate high power mesoband electromagnetic pulse,the frequency response character of a coupled-output mesoband oscillator was analyzed using impulse response method.Firstly we derived the response function of the oscillator analytically,the percent bandwidth of the output pulse against the couple coefficient of the coupler was obtained as well.A coupler with nearly constant couple coefficient of 0.6 at 200-500 MHz was optimized by Taguchi method,then simulation of the oscillator working processing was performed using axial symmetric 2-D FDTD method,and the simulated frequency spectrum and bandwidth matched well with the theoretical results.关键词
