Abstract
This work explores the performance of a 1-bit dual-linear polarised varactor-based metasurface design at sub-6 GHz. A modified particle swarm optimisation algorithm was utilised to determine the element geometry resulting in minimum reflection loss and phase error, and maximum cross-polarisation isolation. Unit cells may be individually addressed and with independent polarisation control over 3.3 to 3.7 GHz. A prototype consisting of an arrangement 48 x 16 unit cells has been fabricated for deployment in a reconfigurable intelligent surface-aided wireless communication channel sounding campaign.
