Despite the promising applications, plasmonic research faces several challenges:
Material Losses: Metals like gold and silver suffer from intrinsic losses, which can limit the efficiency of plasmonic devices. Scalability: Manufacturing plasmonic structures at large scales while maintaining precision remains a challenge. Stability: Plasmonic materials can degrade over time, especially in harsh environments.
Addressing these challenges requires ongoing research and innovation in material science and nanofabrication techniques.
