I'm doing a simulation of the interaction between RF waves and the particles in the high power amplification devices (such as Magnetron). The Magnetron is constructed of two concentric cylinders with the output cylinder has corrugations in its inner wall ( these corrugations some times is called Vanes).
Now, the questions are:
1-How can i draw these corrugations in the inner wall of a 3D cylinder ? i could draw a two concentric cylinders but i couldn't make corrugations in the inner wall of the outer cylinder. These corrugations are actually made by putting thin metal plates has the same height of the cylinder and distributed around the circle at equal angles. But how can i make this ? Then, How can i glow the final drawings all together to be a one unit?
2- How can i make the input of the cavity at the bottom of those two cylinders? , i cant make excitation !
Thank you in advance.
