Waves of all types inevitably spread out while propagating, owing to diffraction. Under certain strict conditions, however, waves can be made to propagate without diffraction. Although this has been ...

Proceedings of the Royal Society of London. Series A, Mathematical and Physical Sciences, Vol. 209, No. 1096 (Oct. 8, 1951), pp. 81-96 (16 pages) The radio waves from 'radio stars' may suffer ...

THE experimental results reported in a previous communication 1 confirm the existence of several maxima for the second- and the third-order diffraction lines at oblique incidence and at low sound ...

This is a preview. Log in through your library . Abstract The diffraction of axisymmetric, harmonic elastic waves by a circular crack is considered. It is shown that the potential functions for the ...

Diffraction phenomena are of fundamental importance for the characterization and analysis of materials in industrial and scientific applications. Prominent examples include X-ray crystallography as ...

A new imaging technique that uses electron diffraction waves to improve both image resolution and sensitivity to small structures has been developed by scientists at the University of Illinois at ...

sound waves cause air particles to vibrate back and forth ripples cause water particles to vibrate up and down Waves cause a disturbance of the medium through which they travel. This allows them to ...
