Thus, a periodic structure with a high refractive index is obtained.

Each unit of the prescribed periodic structure acts like large scale atoms.

Also, as part of periodic composite structure these are designed to have a stronger magnetic coupling than is found in nature.

As required by the above definition, these sheets have a periodic internal structure.

The two different semiconductor materials are deposited alternately on each other to form a periodic structure in the growth direction.

More interestingly, has been the recognition that the periodic structure is actually not the best solution for many applications.

Patterning and periodic structures are very important in physics.

A lattice is the repeating or periodic structure of a crystal.

They are up to 20 times more efficient at second-harmonic generation than crystals of the same material without periodic structure.

The periodic structure is created in the crystal using a range of techniques.
