Relationship between the resonant frequency and strain level of L.

Strain (%)	CSRR #1 (GHz)	CSRR #2 (GHz)
0	2.03	3.68
11.42 = 5.71 (along +x direction) + 5.71 (along −x direction)	1.97	3.52
22.84 = 11.42 (along +x direction) + 11.42 (along −x direction)	1.92	3.37
34.28 = 17.14 (along +x direction) + 17.14 (along −x direction)	1.86	3.25
45.72 = 22.86 (along +x direction) + 22.86 (along −x direction)	1.78	3.13
