Cross-polarized wave generation — Fig. 1. Cross polarized wave (XPW) generation is a nonlinear optical process that can be classified in the group of frequency degenerate [four wave mixing] processes. It can take place only in media with anisotropy of third order nonlinearity. As … Wikipedia
Interference (wave propagation) — Two point interference in a ripple tank. In physics, interference is the phenomenon in which two waves superpose each other to form a resultant wave of greater or lower amplitude. Interference usually refers to the interaction of waves that are… … Wikipedia
Pp-wave spacetime — In general relativity, the pp wave spacetimes, or pp waves for short, are an important family of exact solutions of Einstein s field equation. These solutions model radiation moving at the speed of light. This radiation may consist of:*… … Wikipedia
Rogue wave — This article is about the deep ocean rogue waves which occur far out at sea. For tsunami and tidal wave phenomena, see those respective articles. For other uses, see Rogue wave (disambiguation). The Draupner wave, a single giant wave measured on… … Wikipedia
fundamental interaction — In physics, the effect of any of the four fundamental forces gravitational, electromagnetic, strong, and weak. All known natural forces can be traced to these fundamental interactions. Gravitation is the attractive force between any two objects… … Universalium
Nonlinear optics — (NLO) is the branch of optics that describes the behaviour of light in nonlinear media, that is, media in which the dielectric polarization P responds nonlinearly to the electric field E of the light. This nonlinearity is typically only observed… … Wikipedia
Metamaterial 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… … Wikipedia
Metamaterial — Negative index metamaterial array configuration, which was constructed of copper split ring resonators and wires mounted on interlocking sheets of fiberglass circuit board. The total array consists of 3 by 20×20 unit cells with overall dimensions … Wikipedia
Mathematics of radio engineering — A complex valued function. The mathematics of radio engineering is a pleasant and very useful subject. This article is an attempt to provide a reasonably comprehensive summary of this almost limitless topic. While the ideas have historically… … Wikipedia
Chicken Invaders — is a series of shoot em up video games, developed by InterAction Studios and released for Microsoft Windows, Mac OS X and Linux systems. Currently, there are four video games in the series, along with three special editions. The main theme of the … Wikipedia
