Modeling of Diffractive-/Metasurfaces and Their Performance Evaluations in General Optical System

24 August 2020 | 14:40 – 15:00 (PTD)

We will present a physical-optics-based approach to deal with the modeling of the whole diffractive-/metasurfaces, by decomposing the input field into numbers of sub-fields and studying the interaction of each sub-field with a local extension of the surface.

Insights into Physical Optics with VirtualLab Fusion for Optics Education

26 August 2020 | 16:30 – 16:50 (PTD)

With the help of VirtualLab, we will demonstrate several classical physical optics effects, for example, diffraction from slits, Talbot effect, Arago spot (Poisson’s spot), Michelson/Mach-Zehnder/Young’s interferometers, Gouy phase shift, Goos-Hänchen shift, and so on.

Modeling and Design of Metagratings

2 September 2020 | 10:00 – 11:00 & 17:00 – 18:00 (CET)

VirtualLab Fusion provides a seamless workflow for design and analyzing metagratings – from the unit cell (single pillar) selection, the composition of metagratings by using pillars with varying parameters, and the parametric optimization of the metagrating structure for further performance improvement. All the steps can be done in the unified simulation platform VirtualLab Fusion, and, in this webinar, we will demonstrate the workflow above at selected examples.
