101GRENOUILLE — Grating eliminated no nonsense observation of ultrafast incident laser light e fields (GRENOUILLE) is an ultrashort pulse measurement technique based on frequency resolved optical gating (FROG). The somewhat frivolous acronym was chosen because… …
102Inertial wave — Inertial waves, also known as inertial oscillations, are a type of mechanical wave possible in rotating fluids. Unlike surface gravity waves commonly seen at the beach or in the bathtub, inertial waves travel through the bulk of the fluid, not at …

105Crystal momentum — In solid state physics crystal momentum or quasimomentum[1] is a momentum like vector associated with electrons in a crystal lattice. It is defined by the associated wave vectors k of this lattice, according to (where is the reduced Planck s… …
106nuclear fission — fission (def. 2). [1885 90] * * * Division of a heavy atomic nucleus into two fragments of roughly equal mass, accompanied by the release of a large amount of energy, the binding energy of the subatomic particles. The energy released in the… …

109Chirped pulse amplification — Diagramatic scheme of chirped pulse amplification. Chirped pulse amplification (CPA) is a technique for amplifying an ultrashort laser pulse up to the petawatt level with the laser pulse being stretched out temporally and spectrally prior to… …
110Metamaterial antenna — This Z antenna tested at the National Institute of Standards and Technology is smaller than a standard antenna with comparable properties. Its high efficiency is derived from the Z element inside the square that acts as a metamaterial, greatly… …
