Abstract

Meta-surfaces are becoming an integral part of next-generation wireless systems, and among them, Reconfigurable Intelligent Surfaces (RIS) stand out as a transformative technology. RIS are passive, reconfigurable meta-surfaces capable of dynamically controlling the reflection of electromagnetic waves without the need for active transmission components. This makes them an energy-efficient alternative to conventional active antenna arrays, offering similar beam-steering capabilities with dramatically reduced power consumption.

In the context of 6G, RIS are expected to revolutionize wireless channel modeling by enabling reliable signal paths even in non-line-of-sight (NLOS) environments where traditional propagation is obstructed or scattered. Beyond enhancing coverage, RIS can be combined with an antenna system and deployed as an alternative to active antenna arrays.

Highlights:

This webinar offers a practical and comprehensive introduction to the design and simulation of RIS. Participants will gain insights into:

• Unit cell design
• Quantization effects and their impact on beamforming
• Full-panel modeling and simulation
• Key use cases where RIS can be deployed effectively
