Asymmetric Metamaterial Waveguides

Autor: Zhaowei Liu, Vitaly Felix Rodriguez Esquerre, Juarez Caetano da Silva

Publikováno v: 2020 IEEE Photonics Conference (IPC).

We study asymmetric waveguides with hyperbolic multilayer metamaterial claddings surrounding dielectric cores, in the optical communication band. Each lamellar structure differs simultaneously in its metal layer nature and metal filling ratio. The pr

Publikováno v: Advanced Photonics for Communications.

Power coupling between different size waveguides have been successfully and efficiently optimized by using an evolutionary algortithm based on the artificial immune system in conjunction with the finite element method.
