In this review paper, several strategies for the implementation of reconfigurable split ring resonators (SRRs) based on RF-MEMS switches are presented. Essentially three types of RF-MEMS combined with split rings are considered: (i) bridge-type RF-MEMS on top of complementary split ring resonators CSRRs; (ii) cantilever-type RF-MEMS on top of SRRs; and (iii) cantilever-type RF-MEMS integrated with SRRs (or RF-MEMS SRRs). Advantages and limitations of these different configurations from the point of view of their potential applications for reconfigurable stopband filter design are discussed, and several prototype devices are presented.
在这篇综述论文中,介绍了几种基于射频微机电系统(RF-MEMS)开关实现可重构分裂环谐振器(SRR)的策略。本质上考虑了三种与分裂环相结合的RF-MEMS类型:(i)互补分裂环谐振器(CSRR)顶部的桥式RF-MEMS;(ii)SRR顶部的悬臂式RF-MEMS;以及(iii)与SRR集成的悬臂式RF-MEMS(或RF-MEMS SRR)。从它们在可重构阻带滤波器设计中的潜在应用角度讨论了这些不同配置的优缺点,并展示了几个原型器件。
