I know English is not your first language, but I really can't understand any of that. Can you explain more clearly? If not, post in Chinese and I'll try to translate.

ok
就是说，我想要实现一个设备，可以在垂直面上辐射微波，就像是在一个杆上的每个微面元上所辐射的微波是等效的。等同于一个圆柱体的某一条母线上辐射出的微波，在该母线上的单位元上微波的频率是一致的。这个装置要怎么设计？我知道微波是全方位传播的，但是怎么才能实现使微波充满一个圆柱体，使里面的微波辐射的几乎处处相等呢？
