A photonic crystal is a periodic lattice of dielectric media that prohibits light waves of specific wavelengths from propagating in certain directions.
Once the diffraction peaks from single crystals (or lines from powders) have been indexed in six dimensions, or in three with six basis vectors, and their corrected intensities measured, the diffraction pattern can be considered either on a three-dimensional reciprocal quasilattice or on a six-dimensional periodic lattice.

When you have atoms arranged in a periodic lattice, electrons can flow very easily as they essentially know what to expect," Agarwal said.
In the last part, the applications of SEM to various structural dynamics problems are introduced, including beams, plates, pipelines, axially moving structures, rotor systems, multi-layered structures, smart structures, composite laminated structures, periodic lattice structures, blood flow, structural boundaries, joints, structural damage, and impact forces identifications, as well as the SEM-FEM hybrid method.
This approach can be used to build periodic lattices from optically active particles, such as gold, silver and any other material that can be modified with DNA, with extraordinary nanoscale precision," said Mirkin, director of Northwestern's International Institute for Nanotechnology.
