As the worldwide deployment of 5th generation wireless communication speeds up, groundbreaking research efforts led by both academia and industry are currently in progress to shape and define the next generation wireless technology, known as 6G. Diverging from previous generations, 6G will deliver a revolutionary wireless network that transitions from “connect things” to “connect intelligence”.  

Achieving this vision necessitates the establishment of a smarter electromagnetic wireless environment by using reconfigurable intelligent electromagnetic devices. The most attractive benefit for the intelligent reconfigurable electromagnetic devices is that it can provide a fast, passive, low-cost and low-power consumption beam-forming capability without using multiple expansive RF chains and phase shifters. The reconfigurability transfers the dummy fixed metals to smartly adaptive devices.

In this talk, I will share my recent research progress on the design of reconfigurable intelligent antennas and surfaces. A general design model that unifies the reconfigurable antennas and surfaces design will be first introduce. Then, three design examples including a horizontally polarized highly pattern-reconfigurable antenna, a low-profile vertically polarized highly pattern-reconfigurable antenna and a novel highly phase-reconfigurable intelligent surface will be introduced in detail. Their performance and applications will also be discussed.
