Wave propagation — is any of the ways in which waves travel through a waveguide.With respect to the direction of the oscillation relative to the propagation direction, we can distinguish between longitudinal wave and transverse waves.For electromagnetic waves,… … Wikipedia
Beam propagation method — (BPM) refers to a computational technique in Electromagnetics, usedto solve the Helmholtz equation under conditions of a time harmonic wave. BPM works under slowly varying envelope approximation, for linear and nonlinear equations.The beam… … Wikipedia
Wireless energy transfer — or wireless power is the transmission of electrical energy from a power source to an electrical load without artificial interconnecting conductors. Wireless transmission is useful in cases where interconnecting wires are inconvenient, hazardous,… … Wikipedia
Belief propagation — is a message passing algorithm for performing inference on graphical models, such as Bayesian networks and Markov random fields. It calculates the marginal distribution for each unobserved node, conditional on any observed nodes. Belief… … Wikipedia
Non-line-of-sight propagation — Non line of sight (NLOS) or near line of sight is a term used to describe radio transmission across a path that is partially obstructed, usually by a physical object in the innermost Fresnel zone. Many types of radio transmissions depend, to… … Wikipedia
High Energy Astronomy Observatory 3 — The last of NASA s three High Energy Astronomy Observatories, HEAO 3 was launched 20 September 1979 on an Atlas Centaur launch vehicle, into a nearly circular, 43.6 degree inclination low Earth orbit with an initial perigee of 486.4 km.The normal … Wikipedia
Sound energy flux — The sound energy q results from the integral particle velocity v of the surface A , whereby only the portions perpendicularly to the surface acoustic velocity are important.:q = int overrightarrow{v} , overrightarrow{mathrm{d}A}The sound energy… … Wikipedia
