FEKO中PO算法的区别

我也想知道，同求！

RAY TRACING 指的是所建的模型给定一个入射波方向后，通过射线追踪方法确定其可见区，always illumated指的是所建模型都被认为是可见区域，而最后一种指的是目标前方可见，后向不可见。个人理解

自己可以研究一下软件自带的帮助
Physical optics (PO) - full ray-tracing: The high frequency physical optics method
is used when calculating the currents on the face. In this method, a significant
fraction of the solution time is spent on ray tracing (determining which elements
are visible from each non-PO radiating current). The advanced PO options (see
section 6.10) allow manual optimisation of ray tracing.
Physical optics (PO) - always illuminated: This option is applicable when the model
is such that the entire surface will always be illuminated (such as for a basic reflector
antenna analysis). Shadowing is not analysed, and non-PO surfaces are considered
transparent for this purpose.
Physical optics (PO) - only illuminate from front: This option is applicable to all
closed bodies, but the normal vector must point outward (away from the closed
body) from each face.
自己琢磨去。

谢谢分享   谢谢

Physical optics (PO) - full ray-tracing: 需要通过ray tracing找到那些能够被照射到的面；
Physical optics (PO) - always illuminated: 无需通过ray tracing找到那些能够被照射到的面，假设都能够被照射到；
Physical optics (PO) - only illuminate from front: 封闭曲面的外表面被照射到。
个人理解，供参考！
