Optical Metastructures

Through recent advances in technology, the manufacture of components that use subwavelength structures capable of replicating certain desired emerging properties has become possible for a growing number of applications.

Simulation technology for these so-called metamaterials comes with its own set of challenges, mainly due to the nanoscale structure and high refractive index contrast. The extremely flexible interoperability of modeling techniques offered on a single platform by the optical modeling and design software VirtualLab Fusion allows us, also in this scenario, to adjust the speed-accuracy balance of the simulation to obtain results which are as accurate as needed, as fast as possible. 

Take a look at the use cases linked below to find an example showcasing the design of a metalens based on a subwavelength pillar structure.

There is also a deep-dive document explaining the details of our pillar medium, used to model the metalens component in said example. 

Design and Analysis of a Metalens

In this use case, a focusing metalens based on dielectric, cylindrical pillars is designed and analyzed in detail. The parameters used follow a publication by E. Bayata (2022).

Metagrating Construction – Discussion at Examples

Based on selected examples, we illustrate the construction and configuration of metagrating structures in VirtualLab Fusion.
