中文摘要:基于TE01圆电模研究了椭圆型准光模式变换器,并提出用于快速设计椭圆结构准光系统的修正公式。利用修正公式设计的准光系统由椭圆型Vlasov辐射器与准抛物面镜组成。计算仿真结果表明,该椭圆体系所辐射的波束具有辐射方向性更好,副瓣增益更低的特性,并且其尺寸相比于传统的圆体系更小。

Theory modification and design of elliptical quasi-optical mode converter for Ka-band quasi-TE01 mode
Abstract:Based on TE01 circular electric mode, the elliptical quasi-optical mode converter is studied, and a modified formula for rapidly designing elliptical-structure quasi-optical system is proposed. The quasi-optical system designed by the modified formula is composed of an elliptical Vlasov launcher and a quasi-paraboloidal mirror. The simulation results show that the beam launched by the elliptical system has the characteristics of better launcher directionality and lower side-lobe gain, and its size is smaller than the traditional circular system.
