From: A Mie resonant antenna with high sensitivity for force and strain measurement

(a) The measured relationship between the compressive stress and strain for the silicone rubber. (b) The simulation setup in the CST microwave studio. (c) The simulated transmission spectra curves of the dielectric Mie resonant antenna under different compressive force levels. (d) The calculated relationship between the frequency shift and the applied force. The inset of (d) shows the simulated frequency shift at five loading levels from 0 N to 1 N.
