Metasurface Augmented Lens Antennas
2022 International Workshop on Antenna Technology (iWAT), 2022 In this paper the theoretical methodology of lens antennas augmented with metasurfaces is proposed and demonstrated with a 28 GHz 2D Luneburg lens. The paper presents details on a method of images to design a metasurface augmenting a lens antenna. The cases of PEC reflector and metasurface reflector are considered and a 28 GHz Luneburg lens has been ...

Power balance and efficiency of metasurface antennas [PDF]
Scientific Reports, 2020 AbstractThis paper presents two methods for the efficient evaluation of the power balance in circular metasurface (MTS) antennas implementing arbitrary modulated surface impedances on a grounded dielectric slab. Both methods assume the surface current in the homogenized MTS to be known.

Flat Gain Broadband Metasurface Antennas [PDF]
IEEE Transactions on Antennas and Propagation, 2021 Modulated metasurface (MTS) antennas can provide a broadside pencil beam at the frequency where the cylindrical surface wave (SW) wavelength matches the period of the impedance modulation. For modulations with constant period, the mismatch between the SW wavelength and the period imposes a limitation on the gain-bandwidth product.
