SUPPORTING INFORMATION:
Coupled systems composed of asymmetric resonator elements have sym
metric and antisymmetric
resonances. In the manuscript, only the antisymmetric resonances ar
e reported for the SRR-bar and
ACSRR cases, as the amount of tuning is larger and more strongly
dependent on the coupling distance
than for the symmetric resonance. In Figure S1, the wavelength rang
e is extended in order to show how
both the symmetric and the antisymmetric mode are affected by t
he sample strain. In the case of the
SRR-bar, the symmetric mode, which is largely due to the nanowire
resonance, is almost completely
unaffected by changing the coupling distance with the other resonator. T
his was discussed in greater
detail in previous work

Figure S1.
The reflectance data for the SRR-bar coupled resonator array. The
se are the same data as in
Figure 2b (Experiment); however, here, the reported wavelength range i
s extended to shorter
wavelengths in order to show both the symmetric and antisymmetric resonant modes.
