Abstract

A FAV is novel voxel-based 3D data format in which the voxels can hold attribute information such as materials, colors, modeling parameters, or physical values. FAV is expected to be used for various kinds of simulations or for modifying the design of the object based on the results of measurement data from various sensors. We applied the attribute information for designing metamaterials structure for the first time. Attribute information is registered in each voxel of 3D data by specified directional penetrate projection of two-dimensional raster data or overlaying of three-dimensional raster data. Locally modified metamaterials structure is embedded into 3D data by using a 3D threshold value matrix which represents the shape of unit of metamaterial element and digital halftone screening technology. The 3D threshold value matrix is generated for any type of metamaterials based on the existence probability of voxel arrangement of the unit of metamaterial element. With the technologies, three-dimensional physical property values' distributions can be easily converted to locally modulated metamaterials structure, which can be expected various industrial use.
