| 摘 要： | 高功率微波运用的圆波导劈形端口辐射器(Vlasov-Nakajima辐射器)的辐射场可视为由平开口圆波导的辐射场和在该辐射场中的劈形圆波导段的散射场叠加而成。运用等效电磁流原理数值求解Kirchhoff-kottler积分获得圆波导TM01模的辐射场，再应用物理光学方法计算劈形段的散射场，并将计算的远场方向图与实验结果比较，获得较满意的一致。

NUMERICAL ANALYSIS OF A CIRCULAR WAVEGUIDE BEVEL CUT RADIATOR |
| |
| Abstract: | This paper addresses the numerical analysis method for a circular waveguide bevel cut radiator (Vlasov-Nakajima radiator) which is used as the first step in the design of a high power microwaveVlasov-type mode converter. The radiation field launched from the radiator can be considered as the sum ofthe field radiated by the circular aperture and the field scattered by the bevel cut. The former is predicated byKirchhoff-Kottler integration. The latter is calculated by physical--optics approach. Numerical far-field radiation patterns are compared to measured results. The theoretical analysis of the frequency characteristic of theradiator shows that it has limitary electrical scan ability. |
