Exact solutions of nonlinear differential equations are of great importance to the theory and
practice of complex systems. The main point of this review article is to discuss a specific …

In this study, we propose an equivalent circuit of a metamaterial 1D waveguide. The latter is
made of a diphasic medium to induce both non-linearity and dispersion. The balance …

In this work, the impact of the higher-order reactive nonlinearity on very high-amplitude
solitons of the cubic–quintic complex Ginzburg–Landau equation is investigated. These high …

The guiding mechanisms of both photonic bandgap and inhibited coupling hollow-core
photonic crystal fibers (HC-PCFs) are discussed, a special attention being paid to kagome …

Nowadays the development and implementation of optical networks is unstoppable. Up-to-
date knowledge in this area is essential for engineers. The training of this subject is …
