本文描述了利用回旋管进行电子回旋加热时,开口波导向等离子体辐射微波的辐射方向图的计算方法。简要地介绍了理论推导过程,给出了2cm开口圆波导H_(01)~0模和开口矩形波导模的E面和H面的辐射方向图,以及8mm开口圆波导H_(02)~0模和开口矩形波导模的E面和H面的辐射方向图。
This paper describes a method of calculating the radiation pattern of microwaves radiated by an aperture waveguide to the plasma when the electron cyclotron heating is performed using a gyrotron. The theoretical derivation process is briefly introduced. The radiation patterns of the E and H planes of a 2cm circular waveguide H_ (01) ~ 0 mode and an open rectangular waveguide mode are given, and the H_ (02) ~ 0 mode of the 8mm circular waveguide And the radiation pattern of the E-plane and the H-plane of the open rectangular waveguide mode.
