由近轴近似得到了有源加载准光腔的矢量波函数,并由矢量波函数展开方法得到了有源加载情况下准光腔中的并矢格林函数。由此可以得到腔中电磁场的积分解。
The vector wave function of the quasi-optical cavity with active loading is obtained by the paraxial approximation. The dyadic Green’s function in the quasi-cavity with the active loading is obtained by the vector wave function expansion method. From this we can get the integral solution of the electromagnetic field in the cavity.
