Mathematical modelling of plasmonic strain sensors

by H. Ammari and P. Millien and A. Vanel

(Report number 2020-12)

Abstract
We provide a mathematical analysis for a metasurface constructed of plasmonic nanoparticles mounted periodically on the surface of a microcapsule. We derive an effective transmission condition, which exhibits resonances depending on the inter-particle distance. When the microcapsule is deformed, the resonances are shifted. We fully characterise the dependence of these resonances on the deformation of the microcapsule, enabling the detection of strains at the microscale level. We present numerical simulations to validate our results.

Keywords: plasmonic resonance, biomedical imaging, metasurface, strain sensing
