Willie Padilla - Deep Learning the Next 20 Years of Electromagnetic Metamaterials
Updated: November 19, 2024
Summary
The video acknowledges recent progress in deep learning for metamaterials and explores the motivation behind using this technology. It explains metamaterials as artificially engineered structures with unique electromagnetic properties, discussing their formation, scalability, and exotic effects. The limitations of traditional metal-based metamaterials are highlighted, prompting consideration of dielectric resonators as an alternative. Deep learning is proposed as a powerful tool for designing metamaterials, generating data, and predicting spectral responses, overcoming challenges in inverse design through well-posed and ill-posed problem solutions.
