Innovation in underlying materials was evident at MWC 2024 in various settings, extending beyond antennas to intelligent surfaces out in the wireless transmission domain. Designs are motivated increasingly by environmental consideration as well as RF performance. There are four categories of application for novel materials relating to the device itself, semiconductors, displays, device body, and the antennas. Reconfigurable Intelligent Surfaces (RIS) constitutes a fifth category beyond the device that has come into play under 5G, particularly at the higher mmWave frequencies above 7 GHz, where ability to optimize transmission without line of sight (LOS) has become a major goal. The requirement for LOS inhibits performance and coverage in high rise urban areas especially, resolved only through excessive densification, which is…
