摘要

Abstract

Pursuing higher data rate with limited spectral resources is a longstanding topic that has triggered the fast growth of modern wireless communication techniques. However

the massive deployment of active nodes to compensate for propagation loss necessitates high hardware expenditure

energy consumption

and maintenance cost

as well as complicated network interference issues. Intelligent metasurfaces

composed of a number of subwavelength passive or active meta-atoms

have recently found to be a new paradigm to actively reshape wireless communication environment in a green way

distinct from conventional works that passively adapt to the surrounding. In this review

we offer a unified perspective on how intelligent metasurfaces can facilitate wireless communication in three manners: signal relay

signal transmitter

and signal processor. We start by the basic modeling of wireless channel and the evolution of metasurfaces from passive

active to intelligent metasurfaces. Integrated with various deep learning algorithms

intelligent metasurfaces adapt to cater for the ever-changing environments without human intervention. Then

we overview specific experimental advancements using intelligent metasurfaces. We conclude by identifying key issues in the practical implementations of intelligent metasurfaces

and surveying new directions

such as gain metasurfaces and knowledge migration.
