Metallic metasurfaces operating at Ku-band and suitable for high-power microwave applications are presented. They are made of cheap off-the-shelf metal sheets and synthesized based on the near-field phase transformation principle. Two pairs of non-uniform slots are etched in the center of the thin metal sheet, and such identical layers are stacked to form the phase-shifting cell. Slots' lengths can control the full 360° phase range with high transmission efficiency. Cells are strategically arranged to form the near-field phase transforming metasurfaces (NF-PTMs). They are innovatively applied to enhance the antenna gain by two-fold and steer the antenna beam within the 104° large conical space. In addition, the proposed NF-PTMs have a power handling capability of 1.9 GW level.
