The extreme manipula tion of fields has been made possible by the fine spatial control and wide range of material properties that can be attained through subwavelength s tructuring.   Research in this area has resulted in devices which overcom e the diffraction limit\, render objects invisible\, and even break time r eversal symmetry. It has also led to flattened and conformal optical syste ms and ultra-thin antennas.  This seminar will identify recent advances i n the growing area of metamaterials\, with a focus on metasurfaces: two di mensional metamaterials. The talk will explain what they are\, the promise they hold\, and how these field-transforming surfaces are forcing the ret hinking of electromagnetic/optical design.\n\nElectromagnetic metasurfaces are finely patterned surfaces whose intricate patterns/textures dictate t heir electromagnetic properties. Conventional field-shaping devices\, such as lenses in prescription eye glasses or a magnifying glass\, require thi ckness (propagation length) to manipulate electromagnetic waves through in terference. In contrast\, metasurfaces manipulate electromagnetic waves ac ross negligible thicknesses through surface interactions\, by impressing a brupt phase and amplitude discontinuities onto a wavefront. The role of th e visible (propagating) and invisible (evanescent) spectrum in establishin g these discontinuities will be explained. In addition\, it will be shown how metasurfaces allow the complete transformation of fields across a boun dary\, and how this unique property is driving a new generation of ultra-c ompact electromagnetic and optical devices with unparalleled field control .  Metasurfaces will be described that exhibit various field tailoring ca pabilities including multiwavelength and multifunctional performances and extreme field shaping. In addition\, metasurfaces with multi-input to mult i-output capabilities will be presented that open new opportunities in ada ptive and trainable designs.\n\nBiography\nAnthony Grbic received the B.A. Sc.\, M.A.Sc.\, and Ph.D. degrees in electrical engineering from the Unive rsity of Toronto\, Canada\, in 1998\, 2000\, and 2005\, respectively.
