Abstract: Deep learning has greatly advanced metasurface design by overcoming the slow, inefficient and experience-driven limitations of traditional numerical simulations. However, inverse design of ...

A new metasurface design lets light of different spins bend, focus, and behave independently—while staying sharp across many colors. The trick combines two geometric phase effects so each spin channel ...

A team of researchers at Penn State have devised a new, streamlined approach to designing metasurfaces, a class of engineered materials that can manipulate light and other forms of electromagnetic ...

Abstract: Training a deep learning (DL) model with data collected from full-wave simulations to accurately estimate electromagnetic responses has become a prevalent approach for metasurface ...

WASHINGTON, May 30, 2023 – Holograms are often displayed in science fiction as colorful, life-sized projections. But what seems like the technology of the future is actually the technology of the ...

A new publication from Opto-Electronic Science; DOI 10.29026/oes.2023.220019 considers chiral Detection of Biomolecules Based on Reinforcement Learning. As one of basic physical properties, chirality ...

Recently, deep reinforcement learning (DRL) for metasurface design has received increased attention for its excellent decision-making ability in complex problems. However, time-consuming numerical ...

Innovative techniques play important roles in photonic structure design and complex optical data analysis. As a branch of machine learning, deep learning can automatically reveal the inherent ...

The increasing demand on a versatile high-performance metasurface requires a freeform design method that can handle a huge design space, which is many orders of magnitude larger than that of ...

In this Letter, we adapt the direct search method to metasurface optimization. We show that the direct search algorithm, when coupled with deep learning techniques for free-form meta-atom generation, ...

Metamaterials are composed of periodic subwavelength metallic/dielectric structures that resonantly couple to the electric and magnetic fields of the incident electromagnetic waves, exhibiting ...
