Sentences with phrase «plane wave»

It is based on the transmission of ultrasonic plane waves into the brain tissue.

«Previous works on nonlinear optical effects in plasmonic oligomers have been based on using plane waves or focused beams with homogenous, i.e., uniform, states of polarizations.

If you know that your electrons are fairly free for example, it is sensible but not essential to start with a basis which includes that property as built in (e.g. augmented plane waves).

During a 1909 lecture in Salzburg, Austria, he said, «I more or less imagine each such singular point [of light] as being surrounded by a field of force which has essentially the character of a plane wave.»

Our work highlights that, even in free space, the invariance of the speed of light only applies to plane waves.

This image depicts the interaction of nine plane waves — expanding sets of ripples, like the waves you would see if you simultaneously dropped nine stones into a still pond.

The sharp acceleration turns the traveling electron wave into a plane wave, like a nice regular pulse of an electron beam with an extremely short wavelength — exactly the kind of beam useful for imaging.

When the plane wave returns and crosses the molecule, it produces an interference pattern with the stationary part of the electron wave function, like two trains of water waves crossing and forming a checkerboard disturbance.

As the plane wave travels along, the pattern oscillates rapidly, causing it to emit ultraviolet radiation that the researchers observe.

An integrated suite of Open - Source computer codes for electronic - structure calculations and materials modeling at the nanoscale, based on density - functional theory, plane waves, and pseudopotentials.

For a plane wave, the average PV = epsilon0.c.E0 ^ 2/2, elementary physics.

Unfortunately both workers failed to understand that the second and subsequent scattering processes were very different from a plane wave (30,000 times more for 500 microns radius).
