Exploring Metamaterial Lasers through Non-Hermitian Scattering Formalism
Abstract
This study explores the exciting properties of metamaterials and their innovative applications in non-Hermitian physics, with particular emphasis on the scattering formalism, a key topic of recent research. We have analyzed how light behaves in a negative index metamaterial (NIM), allowing us to develop a transfer matrix and identify the essential conditions for the occurrence of spectral singularities. These findings are crucial for fine-tuning system parameters that will drive the development of metamaterial slab lasers and coherent perfect absorber (CPA) systems. Overall, our research demonstrates the enormous potential of metamaterials and their significant role in driving innovation in various technology areas.
