Design example: a polarization splitting meta-lens for 1550nm

An attractive feature of meta-surfaces is the ability to encode different functionalities for different incident light, for example wavelength or polarization selective behaviour. This can be achieved by selecting and placing meta-atoms which have simultaneous but different effects for different incident light beams. In this example such a multi-functional meta-surface will be designed. The goal […]

The issue of simulation speed in optimizing meta-surfaces

Why is the calculation time so important? A modern optical design process relies on numerical simulations during nearly all phases of the development cycle. Be it checking the feasibility of a great new idea, optimizing the parameters of a proof-of-concept, identifying risks and tolerances in engineering or combinations of those. Perhaps you’re trying to find […]
