Flexible Intelligent Metasurfaces for Enhanced MIMO Communications [PDF]

ICC 2025 - IEEE International Conference on Communications
Flexible intelligent metasurfaces (FIMs) show great potential for improving the wireless network capacity in an energy-efficient manner. An FIM is a soft array consisting of several low-cost radiating elements. Each element can independently emit electromagnetic signals, while flexibly adjusting its position even perpendicularly to the overall surface ...
