What are the Challenges in Developing Plasmonic Metamaterials?
Despite their promising applications, several challenges need to be addressed:
Fabrication: Creating these materials at a nanoscale with precision remains a significant challenge. Losses: Metals inherently have losses at optical frequencies, which can limit the efficiency of plasmonic devices. Scalability: Developing scalable fabrication methods to produce these materials cost-effectively is still an area of active research. Stability: Ensuring the long-term stability of these materials, especially under operational conditions, is essential.
