在均匀等离子体中麦克斯韦方程的一个严格积分解的基础上给出了若干不同形式的初始光波在其中演化的严格解，包括熟知的平面波解，著名的无衍射波解和三维空间中的球对称无衍射波解。作为一种群速度为零的光束，三维无衍射波的行为是令人惊讶的 Based on a strict integral solution of the Maxwell’s equation in a uniform plasma, a rigorous solution to several different forms of initial light wave evolution is given, including the well-known plane wave solutions, the famous non-diffraction wave solutions, and the spherical symmetry in three-dimensional space No diffraction solution. As a beam with a group velocity of zero, the behavior of three-dimensional undiffracted waves is surprising
