摘要

采用演化方程方法在时域内求解了电流分布均匀的平面圆盘的瞬态辐射问题。用Riemann函数法将电流随时间变化的Klein-Gordon方程以Heaviside函数的形式得到了电磁场各分量的解。利用Duhamel积分，得到了任意时间依赖问题解的推广。研究了不同观测距离和观测角度下辐射场的振幅和能量特性以及励磁电流的时间形状。利用平面圆盘辐射的任意时变问题的解，研究了脉冲辐射在无线电通信和雷达问题中的适用性。

Ultrashort Impulse Radiation from Plane Disk with Uniform Current Distribution

The problem of transient radiation from plane disk with uniform current distribution is solved by Evolutionary Equation method in Time Domain. The solution for all components of electromagnetic field is received by means of Riemann function method for Klein-Gordon equation for time dependence of current in form of Heaviside function. Using Duhamel integral the generalization of the solution for arbitrary time dependence is obtained. Amplitude and energy characteristics of radiated field are investigated for different observation distances and angles as well as time shapes of exciting current. The solution for an arbitrary time dependence of plane disk radiation is used to investigate the applicability of impulse radiation in radio communication and radar problems.
