Abstract

A mechanical tuning technique for architectures employing stacked ring resonators is proposed. The stacked rings are separated by a plastic spring structure allowing the ring spacing to be mechanically adjusted. This technique can be applied to Frequency Selective Surface (FSS) to not only tune the transmission or reflection frequency response, but also reconfigure the functional characteristic of the FSS operation between stop and pass band topologies with applied pressure. A parametric analysis of the novel spring loaded FSS is undertaken in CST simulation software.
