This cascading leads to a strong magneto-inductive
coupling between neghbouting functional layers.
As demonstrated recently, the tight coupling between
adjacent LC resonators through mutual inductance results
in a broadband negative index of refraction wtih low loss,
which is similar to the material response of left-handed transmission
lines.

경우에 해당한다고 하는데, 이 그림이 뭘 의미하는지, 잘 이해가 안됨.
