Outline of Final Research Achievements

We fabricated movable metamaterials that exhibited optical response to minute displacements of air gaps. We successfully demonstrated their optical changes similar to the calculated results. A physical quantity transducer whose transfer function was the structural deformation of a mechanically deformed metamaterial was constructed. Then, movable metamaterial devices as optical force sensors were fabricated and evaluated its characteristics. We could design the device from the viewpoint of designing the transfer function, and find out its optical response characteristics from both theory and experiment.
