In the article "Topological Broadband Invisibility" published in Advanced Optical Materials, Li Zhang, Hongsheng Chen, Yihao Yang, and their colleagues discuss the concept of invisibility cloaks and their limitations. They propose a solution to overcome the narrow bandwidth limitation by positioning objects at topological nodes, which are characterized by minimal electromagnetic field amplitudes and indeterminate phases. The researchers demonstrate this concept using all-dielectric photonic crystal slabs, which have a pair of topological nodes across a wide bandwidth. This research has implications for the development of more effective invisibility cloaks. [Extracted from the article] |
