Forego traditional tips and add a mix of fruits at the edge of your nails. This design features strawberries, oranges, grapes ...

An accurate and simple analytical model for the computation of the reflection amplitude and phase of Reconfigurable Intelligent Surfaces is presented. The model is based on a transmission-line circuit ...

In this paper, a low-profile, broadband reflective metasurface is proposed to generate orbital angular momentum (OAM) beams. The design method of generating is introduced, and the effectiveness of ...
