Hyperbolic Metamaterials for Waveguiding and Polarization Control

The development of metamaterials and metasurfaces has recently led to numerous opportunities in manipulating electromagnetic fields through designing unusual linear and nonlinear optical properties and devices. Variety of metamaterial platforms based on dielectric and plasmonic platforms has been proposed. Hyperbolic metamaterials is a class of anisotropic metamaterials which can be constructed in all frequency ranges from UV to RF using plasmonic or semiconductor nanostructures and components. Due to their specific isofrequency surfaces, they support high wavenumber modes and are crucial for achieving high-resolution imaging, subwavelength waveguiding, enhanced nonlinearities. In this talk, we will overview properties of hyperbolic metamaterials and metasurfaces in both visible and RF spectral ranges and their applications in controlling waveguiding, bio- and chemical sensing and active control of polarisation of electromagnetic radiation.

Anatoly V. ZAYATS is a Chair in Experimental Physics and the head of the Photonics and Nanotechnology at the Department of Physics, King’s College London, where he also leads Nano-optics and Near-field Spectroscopy Laboratory (www.nano-optics.org.uk).
