异常平面波、异常表面波和异常复合波的场分布与它们的非异常对应波的场分布有何关系？这个问题已经在广泛的数值研究中进行了研究，这些研究表明，从普通波到特殊波的过渡只涉及电场和磁场相量以及时间平均坡印亭矢量的平滑变化。因此，就场分布而言，例外的平面波、例外的表面波和例外的复合波实际上与它们在例外波的紧邻方向上传播的非例外的对应波是无法区分的。
How are the field profiles of exceptional plane waves, exceptional surface waves, and exceptional compound waves related to those of their unexceptional counterparts? This matter has been investigated in extensive numerical studies which have revealed that the transition from unexceptional to exceptional waves involves only smooth variations in the electric and magnetic field phasors, and in the time-averaged Poynting vector. Therefore, in terms of field profiles, exceptional plane waves, exceptional surface waves, and exceptional compound waves are practically indistinguishable from their unexceptional counterparts that propagate in directions in the immediate neighborhood of the exceptional waves.
