Polarization conversion using all-dielectric metamaterials

Speaker:
Maria Lorente-Crespo
Affiliation:
Heriot-Watt University
Synopsis:
Under certain conditions, the polarization state of an electromagnetic wave
propagating in free-space may be rotated. As a result, information transferred through a satellite link may arrive corrupted or, worst, lost. Depolarization becomes particularly relevant as satellite communication systems migrate towards higher frequency bands. In this respect, circular polarization is more robust. There are different options for converting linearly to circularly polarized waves. Here all-dielectric metamaterials capable of turning linearly polarized plane waves into high purity circularly polarized waves will be discussed.
Biography:
Maria Lorente-Crespo received the M.Sc. degree in Telecommunications Engineering and in Telecommunication Technologies, Systems and Networks from the Universidad Politecnica de Valencia in Spain, in 2011 and 2012, respectively. From 2010 to 2012 she was employed by the Valencia Nanophotonics Technology Center carrying on research on optical magnetic metamaterials. She is currently working toward the Ph.D. degree at Heriot-Watt University, Edinburgh. Her research interests include the analysis and design of nano-antennas, plasmonic nano-structures and metamaterials applied to antenna systems.
