Evaluation method for optical properties

Possible to check the quality of metamaterials inexpensively, quickly, and accurately.

Overview

　When mass-producing products containing metamaterials, a new method for sorting out good or bad metamaterials is desired because the current conventional technology can not provide an efficient and low-cost detection methods for its large areas.
　The present invention provides an evaluation method for checking the quality of metamaterials that is less expensive than conventional techniques and reduces the time required for evaluation, thus ultimately reducing costs.
