Abstract

This chapter will explore how the reflection properties can be dynamically tuned using reconfigurable surfaces to aid the communication between a transmitter and receiver. We begin by explaining how reflections can be interpreted using the beamforming characteristics from previous chapters and how reconfigurable surfaces can control these characteristics. We will then analyze how these surfaces can be configured to maximize the capacity of narrowband and wideband SISO channels and MIMO channels.
