101Electro-optic effect — An electro optic effect is a change in the optical properties of a material in response to an electric field that varies slowly compared with the frequency of light. The term encompasses a number of distinct phenomena, which can be subdivided… …
102Cross-phase modulation — (XPM) is a nonlinear optical effect where one wavelength of light can affect the phase of another wavelength of light through the optical Kerr effect. Contents 1 Applications of XPM 2 XPM in DWDM applications 3 See also …
103Time-Domain Thermoreflectance — is a method by which the thermal properties of a material can be measured, most importantly thermal conductivity. This method can be applied most notably to thin film materials (up to hundreds of nanometers thick), which have properties that vary …
104Megatron (other incarnations) — As the Transformers franchise has grown, more continuities separate from the original series and its subsidiaries have come into existence, each featuring their own unique version of the Decepticon leader Megatron. Beast Era Megatron was the name …
105endocrine system, human — ▪ anatomy Introduction group of ductless glands (gland) that regulate body processes by secreting chemical substances called hormones (hormone). Hormones act on nearby tissues or are carried in the bloodstream to act on specific target organs… …
106Fourier optics — is the study of classical optics using techniques involving Fourier transforms and can be seen as an extension of the Huygens Fresnel principle. The underlying theorem that light waves can be described as made up of sinusoidal waves, in a manner… …
107Nathan Stubblefield — Nathan B. Stubblefield (November 22, 1860 March 28, 1928) was an American inventor and Kentucky melon farmer. It has been claimed that Stubblefield invented the radio before either Nikola Tesla or Guglielmo Marconi, but his devices seem to have… …
108Microwave transmission — The atmospheric attenuation of microwaves in dry air with a precipitable water vapor level of 0.001 mm. The downward spikes in the graph correspond to frequencies at which microwaves are absorbed more strongly, such as by oxygen molecules… …
109Günter Nimtz — (1936) is a German physicist. Working at the 2nd Physics Institute at the University of Cologne ( Universität zu Köln ) in Germany, he has been conducting experiments that purport to show that under certain conditions, particles may travel faster …
110Meteoroid — A few shooting stars can be seen in this video from the ISS. A Perseid meteor (light streak somewhat to right of center of photo) and Milky Way. A meteoroid is a sand to …
