Abstract
Photonic crystals with periodic variations in dielectric constants can exhibit band gaps in transmission spectra of electromagnetic waves through Bragg diffractions. Introduced structural defects can confine the electromagnetic energies at specific wavelengths, and localized modes of transmission peaks can be formed in above mentioned forbidden gaps. Moreover, thermodynamic crystals with periodically percolated morphologies of metals and ceramics can realize uniform dispersions in thermal and kinetic energies effectively. Introduced artificial dislocations or graded structures into the ideal periodicities realize heat and stress flow controls intentionally. These artificial crystals were processed by micro stereolithography. The electromagnetic wave transmittances, thermal conductivities and mechanical properties for the formed photonic and thermodynamic crystals were measured and compared with simulated results. The photonic and thermodynamic crystals will be applied to novel electromagnetic wave resonators and mechanical tools, respectively. Effective energy flow control with reducing losses will be realized along sustainability
