New degrees of freedom in nonlinear metamaterials

Abstract: This is an overview of the recent achievements in exploiting novel degrees of freedom in metamaterial design, which enable sophisticated nonlinear coupling mechanisms and bring enhancement to nonlinear behavior. One of the novel paradigms makes use of mechanical feedback, achieved by embedding electromagnetic resonators within elastic medium or engineering explicit elastic links between them, such as rotational feedback. These designs provide broad‐band self‐adjustable resonances, self‐oscillations, chaotic re… Show more

“…(A7) into Eq. (A4) and separating the equations for the different powers of ζ , we obtain a set of linear differential equations with the unknown functions Q (1) , Q (2) , and Q (3) , respectively. We further evaluate the magnetic moment of the meta-atom as m = Q S/c and extract the relevant polarizabilities:…”

“…The flourishing field of nonlinear metamaterials [1][2][3] provides a wide variety of ways to implement artificial structures with unusual functionalities [4] including magnetoelastic metamaterials [5][6][7], bistable and self-tunable structures [8][9][10], metamaterials with nonlinear response tuned by the external static field [11][12][13], and metamaterials exhibiting an interplay of electric and magnetic-type nonlinearities [14,15].…”

“…However, metamaterials can exhibit nonlinear magnetic response resulting in a new type of magnetic nonlinearities [32]. This picture is at large adapted in the microwave regime, and a vast number of research groups are engaged in utilizing tailored nonlinear response of metamaterials, as discussed in the recent review papers [33,34]. However, the idea of generic magnetic nonlinearities remains distant to the nonlinear optics community, while new direct observations of the effects induced by magnetic response are being reported, as discussed below.…”

“…Besides, plasmonic resonances of these structures are utilized for other kind of applications such as switches for optical information processing [12]. Strong confinement of the electromagnetic fields on the nano-scale is another feature of the plasmonic resonant structures which allow significant enhancement of weak nonlinear processes [13], [14]. This can be applicable for increasing the nonlinearity of the metal itself or 14 of a material adjacent to the metal [14]- [16].…”
