【摘要】 本文阐述了利用双齿周期结构来实现双频段扭转极化的新思想,并提出了一套方便、可靠的设计方法,即:先利用积分方程法对双齿周期结构进行分析,再利用优化方法进行综合设计。这种方法很好地解决了分析到设计的过渡。通过实验测试,证明本文的理论分析是可靠的、有效的。更多还原

【Abstract】 In this paper, a new idea using a dual-groove periodic corrugated-surface for implementing dual-band twist polarization is described. It is a convenient, reliable method. First, the dual-groove periodic corrugated-surface was analysed with integral equation method. Then, a dual-band twist polarization reflector is designed by using optimization technique. This technique makes the transition from analysis to design possible. The experimental results show that the theoretical analysis is reliable and effective.更多还原
