A terahertz modulator based on the insulator-metal transition (IMT) in a photonic crystal waveguide (PCW) coated by vanadium dioxide (VO2) film is proposed. The numerical simulations show that a dielectric state and a metallic state with quite different photonic band structures and transmission properties in the proposed PCW are reciprocally converted because of the IMT of VO2, and the pass ...

Lead glass, commonly called crystal, is a variety of glass in which lead replaces the calcium content of a typical potash glass. Lead glass contains typically 18–40% (by weight) lead(II) oxide (PbO), while modern lead crystal, historically also known as flint glass due to the original silica source, contains a minimum of 24% PbO.

The simplest optical coatings are thin layers of metals, such as aluminium, which are deposited on glass substrates to make mirror surfaces, a process known as silvering.The metal used determines the reflection characteristics of the mirror; aluminium is the cheapest and most common coating, and yields a reflectivity of around 88%-92% over the visible spectrum.

Original. Originally, rhinestones were rock crystals gathered from the river Rhine, hence the name, although some were also found in areas like the Alps, but today the name "rhinestone" applies only to varieties of lead glass known as crystal glass.The availability was greatly increased in the 18th century when the Alsatian jeweller Georg Friedrich Strass had the idea to imitate diamonds by ...

Oltu stone's most interesting characteristic is its softness when excavated. It only begins to harden when exposed to the air. For this reason, it can be carved very easily. It attracts, by way of static electricity, light substances like dust when rubbed. Oltu stone burns bursting in flames, and leaves ash behind.
