Extreme Field Control with Electromagnetic Metasurfaces

This lecture explores the recent advances in metamaterials, focusing on metasurfaces, two-dimensional metamaterials. It delves into the manipulation of electromagnetic fields through subwavelength structuring, enabling devices that overcome diffraction limits, render objects invisible, and break time reversal symmetry. The seminar discusses the unique properties of electromagnetic metasurfaces, which allow for the complete transformation of fields across boundaries, driving the development of ultra-compact electromagnetic and optical devices with unparalleled field control. It also covers topics such as extreme polarization control, amplitude control, and the design of multi-input to multi-output metasurfaces.
