Tidy3D Modeling of a Non-Hermitian Photonic System
The field of non-Hermitian photonics has seen rapid growth in recent years, with new theoretical insights and experimental demonstrations being reported all the time. Recently, the research group led by Professor Yongmin Liu from Northeastern University demonstrated the precise subwavelength control of light by utilizing the exceptional point in a non-Hermitian system. This work achieved the unidirectional propagation of surface plasmon polariton (SPP) on gold film by engineering a non-Hermitian metagrating structure and has led to a publication in Science...
