Bulk-spatiotemporal vortex correspondence in gyromagnetic double-zero-index media
Ruo-Yang Zhang, Xiaohan Cui, Yuan-Song Zeng +8
Photonic double-zero-index media, distinguished by concurrently zero-valued permittivity and permeability, exhibit extraordinary properties not found in nature. Remarkably, the not…
