MP63 - Elastomer-based flexible THz metasurfaces for sensing applications

For THz sensing systems, reconfigurable metasurface is a key issue for obtaining miniaturized, fast and cheap spectral scanning systems in the THz domain.This paper presents the manufacturing and characterization of flexible elastomer, PDMS (polydimethylsiloxane)-based THz metasurfaces.Numerical models were applied to analyze the system THz properties.Measurements proved the usability of proposed flexible THz sensors.For a 25% deformation, a decrease of resonant frequency by 8% (~ 20 GHz) was obtained.
