Towards dynamic, tunable, nonlinear metamaterials via near field interactions: A review
Metamaterials research continues to bear fruit in the form of novel devices and optics across the electromagnetic spectrum. This is especially true in the gigahertz, terahertz, near infrared frequencies. Metamaterials also continue to be one of the fastest growing subdisciplines of anisotropy research, with most notable metamaterial advances based on inherently anisotropic designs. Despite significant progress, many challenges remain before fully dynamic, broad bandwidth, nonlinear metamaterial devices become truly viable. We review the study of near field interactions, or coupling, in metamaterials with a focus on how manipulation of interactions in metamaterials has helped overcome some of the largest obstacles toward tunable metamaterials, broad bandwidth metamaterials, nonlinear metamaterials, metamaterial experimental techniques. © 2013 Springer Science+Business Media New York.
