Proyecto Coordinado  Versión en Español

The present proposal is framed in a Coordinate Research Project, whose objectives are the design and manufacture of metasurfaces, intended to polarization control, with the final goal of developing applications in the field of microwaves. Thus, new metasurfaces based on printed circuit technology and/or metal substrates, which exhibit intrinsic and/or extrinsic chirality, will be designed, aimed to develop applications such as planar antenna covers meeting the increasing demands of high frequency communication systems (bands X and Ku, among others) in terms of size reduction, antenna complexity, polarization control and/or multi-band operation establishment. The experience acquired in the design of these metamaterials will be applied to the improvement of compact bandpass or band rejection filters in guiding systems at microwave frequencies. In addition, the possibility of tuning these devices will be studied. Moreover, dielectric metasurfaces with high permittivity and low losses are of great interest for the microwave and communications technology because of their potential applications on the aforementioned devices. Therefore, the project does include the numerical design, the study of different manufacturing techniques and the experimental characterization of new configurations susceptible to be used for polarization control. Finally, it will be continued to go deeper into the study and development of unconditionally stable FDTD techniques that provide novelties and improvements with respect to the already existing.

The Coordinated Research Project (MESUMO) is organized into two subprojects whose main orientations are numerical analysis by means of EM simulators (MESUMO-NUM) and the experimental characterization (MESUMO-EXP) of metasurfaces, being both essential approaches for the achievement of the proposed objectives.
