FEKO能用几何光学法仿真反射面天线吗？

可以，金属几何法。

几何光学对单反射面仿真还可以
多个反射面几何光学就不适合了。

请问楼上的，具体怎么设置啊?有没有案例呢》?我研究了一下怎么不行呢》?另外准确性怎么呢

可先了解這個檔案後再作研究
25 Horn feeding a large reflector
Keywords: Waveguide, horn, reflector, PO, aperture source, spherical mode source, equivalent source, decouple, far field
A cylindrical horn is excited with a waveguide port is used to feed a parabolic reflector at 12.5 GHz. The reflector is electrically large (diameter of 36 wavelengths) and well separated from the horn. An illustration of the model is shown in figure 25-1. This example illustrates some of the techniques available in FEKO to reduce the required resources for electrically large models.

这个案例我看了，也会用物理光学算反射面了，但是就是不会几何光学
