Research: Performance Evaluation of Reconfigurable Intelligent Surfaces for Enhanced 6G...

Research question: How do reconfigurable intelligent surfaces impact signal coverage and quality in 6G millimetre-wave indoor communication environments?

Millimetre-wave (mmWave) frequencies are central to 6G wireless systems due to their capacity for high data rates and broad bandwidth. However, mmWave signals suffer from significant propagation losses, blockage, and limited coverage, particularly in indoor environments.

Reconfigurable intelligent surfaces (RIS) have recently emerged as a promising solution to manipulate electromagnetic waves and enhance signal propagation. Despite theoretical advances, empirical data on RIS deployment effectiveness in real indoor 6G mmWave scenarios remains sparse, especially regarding coverage improvements and quality metrics.

This study will systematically review the literature, formulate hypotheses about RIS-driven coverage enhancement, and design a methodology combining electromagnetic simulation and small-scale experiments using programmable metasurfaces. The project will analyze signal strength, coverage area, and reliability with and without RIS in controlled indoor layouts.

Findings will inform practical 6G deployment strategies, bridging the gap between theoretical RIS models and real-world performance. The research is significant for advancing robust, energy-efficient wireless infrastructure in next-generation communication networks.
