从第一原理出发，我们证明了具有特定且唯一确定的远场图案的两个非各向同性辐射体可以一致地建模为两个非耦合的各向同性辐射体，只要其中一个愿意接受几何的非线性失真。这表明，非耦合各向同性本身的非物理模型对于正确描述特殊各向同性辐射体的行为具有物理意义。讨论了必要的几何失真及其后果。
From first principles, we show that two non-isotropic radiators with a specific and uniquely determined far-field pattern can be modeled consistently as two uncoupled isotropic radiators, provided one is willing to accept a non-linear distortion of the geometry. This shows that the, per se, non-physical model of uncoupled isotrops can have physical meaning in correctly describing the behavior of special non-isotropic radiators. The necessary distortion of geometry and its consequences are discussed.
