对用于产生高斯模的双模喇叭进行了改进。以前的设计已经使用突然转变或线性锥化来产生所需的TE/SUB 11/和TM/SUB 11/模混合。在本文提出的改进设计中，使用优化的非线性锥度来产生多模，其基频高斯模功率分数为99%，超过了波纹喇叭的功率分数(98%)。与其他双模喇叭设计相比，带宽和回波损耗都有所改善。
An improvement on the dual-mode horn for Gaussian mode generation has been developed. Previous designs have used a sudden transition or linear taper to generate the required TE/sub 11/ and TM/sub 11/ mode mixture. In the improved design presented here, an optimized nonlinear taper is used to generate multimodes, which have a fundamental Gaussian mode power fraction of 99% that exceeds that of the corrugated horn (98%). The bandwidth and return loss are both improved over other dual-mode horn designs.
