Popup Tunable Frequency Selective Surfaces for Strain Sensing
ieee sensors（2020）
Abstract
A 3-D popup frequency selective surface (FSS) is presented that can be tuned by the amount of strain due to mechanical loading in its elastomeric substrate. The proposed FSS structure comprises periodic 2-D crossed dipoles attached to the substrate at selective bonding sites. Strain release in the substrate induces compressive stress in the attached FSS, converting it to a 3-D periodic pattern. Wi...
