Design and engineering of metasurfaces for high-directivity antenna and sensing applications

摘要

The engineering of metasurfaces for antenna and sensing applications is investigated. The metasurfaces composed of LC-resonant cells, are designed to achieve either modulated phase or high quality factor resonances. While the phase modulated metasurface applied as a superstrate in a Fabry-Perot cavity antenna, shows the capability to steer the radiated beam to an off-normal radiation, the high quality factor resonant metasurface presents high sensitivity to the presence of substances.
