摘　　要：通过有源Maxwell方程对应的电磁场矢量波动方程,利用时域Green函数方法,结合电磁场边界条件,推导出线性、均匀、各向同性的水平层状介质中瞬变波动场入射波的直接时域解析公式。避免了传统偶极子假设和时频转换引起的误差,为解决全场区瞬变电磁精细探测直接时域解析问题提供了理论基础。The vector wave equation of electromagnetic field was given through Maxwell equation.By combining the boundary conditions of electromagnetic field, the linear, even, every different level layered mediums and the time domain response formula of transient wave electromagnetic field were got with time-domain Green function method, which not only avoided the errors caused by the traditional dipole hypothesis and the transformation between the time domain and frequency domain,but also provided the theory basis for solving the problems on the time-domain response.
