Numerical Analysis of Structural Color for Photonic Crystal Hydrogel

Photonic crystal has become a powerful technique for regulating electromagnetic waves due to its excellent features, such as structure designability and dynamic adjustability; in addition, it great application value. In this paper, we visualize colors on the Ostwald color model analyze differences of each group patches via minimum difference model. The manipulation law particle size, temperature, humidity change photonic hydrogel is verified by these analyses.
