Metalens Design App

Application ID: 117281

This is a simple yet powerful simulation app for designing a two-dimensional reflective metalens. This metalens consists of a array of glass nanopillars on a metal substrate. Initially, the app determines the optimal grating parameters for a specific wavelength and calculates the relationship between the nanopillar diameter and relative phase shift. Using this data, the app automatically constructs the geometry of the metalens. Finally, the app conducts a frequency domain study on the finalized geometry to compute the electric field around the focus.

For a description of this example app, see our accompanying blog post "Building a Metalens Design App with COMSOL Multiphysics®".

This application example illustrates applications of this type that would nominally be built using the following products:
