“…Very recently, Modulation instabilities (MI) in a one-dimensional chain configuration of a flexible mechanical metamaterial (flexMM) is reported, here flexMMs can be modeled by a coupled system of discrete equations for the longitudinal displacements and rotations of the rigid mass units [17]. In the variety of works, many authors discussed the modulation instability analysis for metamaterials with different linear and nonlinear effects [18][19][20][21][22][23][24][25][26][27]. In these works, some novel results are attained to understand the modulation instability in metamaterials.…”

We have conducted a study that investigates the complex interactions between different factors in metamaterials, particularly in the context of modulation instability. We have shown the competition between intermodal dispersion, self steepening effect, higher order dispersion and the amplitude of plane waves with variety of modulation instability in metamaterials. The specific behavior of MI bands and their dependence on the self-steepening parameter and amplitude will vary depending on the details of the optical system and the dispersion properties of the medium

Our study delves into the intricate interplay of various factors within metamaterials, with afocus on modulation instability. Through our research, we elucidate the intricate dynamics involving intermodal dispersion, self-steepening effect, higher order dispersion, and plane wave amplitude,showcasing their competition and influence on modulation instability phenomena. We aim to explorethe impact of intermodal dispersion and higher-order effects by numerically solving the generalizednonlinear Schr¨odinger equation (NLSE), which models the propagation of a few-cycle pulse in a nonlinear metamaterial. Our modulation instability (MI) analysis captures the complex dynamics thesefactors introduce. We demonstrate the spatiotemporal evolution of MI under different parametervalues, revealing how these variations influence the instability’s development and characteristics.This approach provides a detailed understanding of the system’s behavior across various conditions,highlighting the roles of intermodal dispersion and higher-order effects. We demonstrate that thebehavior of modulation instability bands and their reliance on parameters such as self-steepeningand wave amplitude is contingent upon the specific characteristics of the optical setup and mediumdispersion properties.
