pure-tone pulse

Taking the short pulse as an ideal delta function on time scale, we find that the radiation field pattern is just of the "pure" waveguide modes if the resonance frequency equals as integral times as radio frequency.

将短脉冲理想化为时间上的δ函数，可以发现当辐射频率正好等于用来调制电子束的射频的整数倍时，辐射模式表现为纯的波导本征模，此时辐射功率最强。
