Synthesis of active metasurface – practical example

Metasurfaces, a class of thin metamaterials, have shown unprecedented capabilities in the local manipulation of phase, amplitude and polarization of electromagnetic waves from microwave to optical frequencies by tailoring the geometry of building elements. At microwave frequencies, they are constituted by sub- wavelength size patches or pins printed on thin grounded dielectric substrates or realized as a texture in a metal surface. During this course the background and basic theory of active reflective metasurfaces were explained, how to avoid instability and how to realize such active metasurfaces for different applications.
