Abstract
A method of designing a meta optical device is provided. The method includes: setting, via a processor, design data for arrangement and dimensions of a nanostructure of the meta optical device, according to a function to be implemented by the meta optical device; obtaining a phase change graph with respect to a change in the dimensions; setting a shape dimension region with phase defect in the phase change graph; and substituting a shape dimension with phase defect, which is included in the shape dimension region with phase defect among the dimensions included in the design data, with a substitution value that is outside the shape dimension region with phase defect. Accordingly, a meta optical device having no phase defect is implemented.
