Preparation method of photonic crystal based on 3D printing and photonic crystal
The invention discloses a photonic crystal based on 3D printing and a preparation method thereof. The preparation method comprises the following steps that S1, slurry is prepared, the elasticity modulus of the slurry is larger than the viscous modulus, the slurry has viscoelastic inversion performance, the slurry is prepared from polydimethylsiloxane and a ceramic material, the slurry is divided into slurry A and slurry B; the dielectric constant of the slurry A is not equal to that of the slurry B; S2, a first crystal layer is formed from the slurry A and forming a second crystal layer from the slurry B by film-free direct-writing 3D printing equipment, and the first crystal layer and the second crystal layer are stacked to form a wood pile structure to obtain a photonic crystal semi-finished product; and S3, the photonic crystal semi-finished product is cured to obtain the photonic crystal. According to the preparation method, the process is simple, the prepared photonic crystal is high in precision, the stealth of terahertz waves with different frequency bands can be realized, and the applied wave band can be in a range of 10 GHz-10 THz.
