(Nanowerk News) Photonic time crystals consist of materials with uniform composition in space but properties that vary periodically over time. With this periodic variation, the spectral composition of ...

This course is designed to provide a theoretical background on the propagation of elastic stress waves in solids with periodic variation in geometry or elastic properties, a review of experimental ...

Jitter is a short-term variation in the timing of a digital signal from its nominal value. There are two main types of jitter, random jitter and deterministic jitter. Random jitter is unbounded, that ...

Schematic of a portion of a 2D hierarchical phoxonic crystal with both large scale photonic lattice and a smaller scale phononic lattice inside a cavity resonator in the larger scale lattice. (Image: ...
