Anisotropic Volume Scattering

Project

When light is incident upon particles with sizes comparable to the wavelength, this light is scattered in different directions. This effect is the reason the sky is blue! The direction of the scattered light is dependent on the geometry and material of the particles. Therefore, it is theoretically possible to design nanoparticles in such a way that the light is scattered into a desired direction. This could potentially be used in many different products: LEDs, diffusers, miniaturized satellites and more.


Objective

In practice it still proves to be difficult to design nanoparticles to have specific scattering behaviour. The reason for this is that the determination of scattering characteristics relies on time-consuming numerical methods. The aim of this research is to establish design rules for scattering nanoparticles and experimentally confirm them, such that they can be used for the development of new products and technologies.


Impact

The result of this research could open up more possibilities in the design of LEDs, improving their efficiency and directionality and diffusers, allowing more control over their properties boosting the quality of optical devices they are incorporated in.
