Extremely asymmetric absorption and reflection near the exceptional point of three-dimensional metamaterial
Yanjie Wu, Ding Zhang, Qiuyu Li +7
In recent years, particular physical phenomena enabled by non-Hermitian metamaterial systems have attracted significant research interests. In this paper, a non-Hermitian three-dim…
