Solitons in Optical Metamaterials by Functional Variable Method and First Integral Approach

This paper addresses soliton solutions in optical metamaterials by functional variable method and first integral approach. These integration schemes lead to bright and singular 1-soliton solution. Topological soliton solution is also revealed. Additionally, as a byproduct, singular periodic solutions and continuous waves are obtained. The corresponding constraint conditions are also listed for these variety of solutions to exist. Finally, a numerical simulation of the bright 1-soliton solution is given.
