Figure 3. (A) Schematic diagram of EM measurement experiment by the free-space method and an image of the extensometer. (B) EM experimental measurements and simulation results of FSS with uniaxial stretching strains of 0%, 5.4%, 11.3% and 21%, respectively. Trends of (C) resonant frequency and (D) -10 dB bandwidth vs. x-axis uniaxial stretching strains. VNA: Vector network analyzer; EM: electromagnetic.
