Engineered Nonlocalities in Metasurfaces
Hosted By: Optoelectronics Technical Group
22 April 2022 9:00 - 10:00Eastern Time (US & Canada) (UTC - 04:00)
Metasurfaces have experienced an explosive research interest since their initial proposal, both in the microwave and in the optical domain. Largely investigated as passive devices, the great flexibility of this technology offers also a unique potential to develop active devices and flat sources of light fields. In this context, some metasurface design approaches are well known and have become common practice but many challenges still remain unanswered. Novel concepts need to be urgently explored.
In this webinar, Prof. Andrea Alù, one of the most renowned researcher in the field, will share his point of view on the topic, presenting the latest developments and the path that he envisions for the future. In particular, he will discuss recent progress in the context of optical metasurfaces with tailored nonlocal responses. He will discuss the current limitations of conventional metasurface approaches, and how nonlocal phenomena can overcome these limits and pave the way to a powerful platform for a wide range of optical functionalities. Based on these principles, He will describe opportunities for ultrathin technologies for advanced imaging, augmented reality, secure communications, analog optical computing and a new generation of light-emitting metasurfaces.
