Abstract: The following relates generally to user selection of parameters to approximate desired properties of light scattering. More specifically, in some embodiments, a graphical user interface (GUI) is provided. In some embodiments, in a forward configuration, the GUI accepts an input parameter that is a physical property or optical property of a nanoparticle material (e.g., nanoparticle size, shape, etc.), and outputs an optical effect of the nanoparticle material (e.g., a color, a graph of a reflectance fraction vs. wavelength, etc.); whereas, in an inverse configuration, the GUI accepts the optical effect as the input, and outputs a physical property or optical property of the nanoparticle material.

Abstract: Exemplary embodiments relate to techniques for determining structural color from parameters of an array of nanopartides. The techniques include inputting structural and optical parameters and performing a probabilistic simulation to determine the structural color. An evolutionary optimization may be performed to determine parameters of the array of nanoparticles according to desired properties of structural color. The evolutionary optimization may employ the probabilistic simulation and further adjust one or more parameters of the array to approximate the desired properties of the structural color. Based on applying the probabilistic simulation, the technique may generate an output describing a value, or a range of values, for the one or more parameters of the array of nanoparticles that are selected to approximate the desired properties of the structural color.
