报告内容: Metasurfaces have been emerged as one of rapidly-developing subjects in science and engineering due to their nature of multi-disciplinary and applications ranging from microwave to optics. Novel manufacturing tools have further enabled the development of metasurface research and intriguing designs have been realized based on the use of nanofabrication techniques and rapid prototyping tools. In this talk, I will focus on how to design new forms of metasurfaces which may overcome the limitation arising from traditional designs based upon the use of periodic structures. I will discuss the possibilities of applying the theory of hyperuniform disorder to overcome unwanted Bragg diffraction. Active materials with tunability and non-Foster theorem will be also introduced in order to overcome the bandwidth limits of metasurfaces. Finally, a common platform for design optimisation of metasurfaces will be presented.
