Extreme Field Control with Electromagnetic Metasurfaces
An in-person presentation by IEEE MTT-S Distinguished Microwave Lecturer and IEEE Fellow Prof. Anthony Grbic from University of Michigan
The research area of metamaterials has captured the imagination of scientists and engineers over the past two decades by allowing unprecedented control of electromagnetic fields. The extreme manipulation of fields has been made possible by the fine spatial control and wide range of material properties that can be attained through subwavelength structuring. Research in this area has resulted in devices which overcome the diffraction limit, render objects invisible, and even break time reversal symmetry. It has also led to flattened and conformal optical systems and ultra-thin antennas. This lecture will identify recent advances in the growing area of metamaterials, with a focus on metasurfaces: two dimensional metamaterials. It will explain what they are, the promise they hold, and how these field-transforming surfaces are forcing the rethinking of electromagnetic/optical design.
Electromagnetic metasurfaces are finely patterned surfaces whose intricate patterns/textures dictate their electromagnetic properties. Conventional field-shaping devices, such as lenses in prescription eye glasses or a magnifying glass, require thickness (propagation length) to manipulate electromagnetic waves through interference. In contrast, metasurfaces manipulate electromagnetic waves across negligible thicknesses through surface interactions, by impressing abrupt phase and amplitude discontinuities onto a wavefront. It will be shown how metasurfaces allow the complete transformation of fields across a boundary, and how this unique property is driving a new generation of low-profile electromagnetic and optical devices with unparalleled field control.
