報告摘要:I will discuss some metamaterial carrying chiral structures that exhibit some interesting properties. That includes networks that have non-trivial topology that can couple orbital angular momenta with the wave vector. Such systems exhibit angular momentum-dependent one-way edge states, and their properties can be described using local Chern numbers. Other examples include systems that can realize ‘anti-duality’, leading to nodal lines in momentum space. Such systems also exhibit one-way edge modes that can be used to achieve optical pulling in a channel.
