Abstract :
We numerically design and study graphene metasurface to modulate the phase of reflective light. Results show that the phase of the reflection can range almost from -π to π just by changing the width of the graphene ribbons, while the amplitude of the reflection can keep in a small variation. By using graphene metasurface, we realize negative reflection and nano focusing.
