A New Design Strategy for Reconfigurability of Smart Electromagnetic Devices

The aim of this contribution is to discuss the possible application of composite vortex theory to introduce a new design strategy for adding reconfigurability to different electromagnetic devices. In particular, the concept of composite vortices will be exploited to control the radiating and reflecting properties of patch antennas and reflective metasurfaces, respectively. Compared to other approaches, this design strategy allows for reducing the number of elements to be controlled and, thus, simplify the practical implementation of reconfigurable antennas and reflective intelligent surfaces, which are fundamental elements of nextgeneration wireless systems.
