:The page means by " cylindrical wave " a wavefront that is spreading on a cylidrical surface.
2.
Their use is discouraged, because they wrongly assume cylindrical waves which would require perfect line sources for reproduction.
3.
The experimental results demonstrated focusing of an incident cylindrical wave within an octave bandwidth and over an electrically short area; suggestive of near-field focusing.
4.
If the width of the slits is small enough ( less than the wavelength of the laser light ), the slits diffract the light into cylindrical waves.
5.
A long slit of infinitesimal width which is illuminated by light diffracts the light into a series of circular waves and the wavefront which emerges from the slit is a cylindrical wave of uniform intensity.
6.
The Hankel functions are used to express outward-and inward-propagating cylindrical wave solutions of the cylindrical wave equation, respectively ( or vice versa, depending on the sign convention for the frequency ).
7.
The Hankel functions are used to express outward-and inward-propagating cylindrical wave solutions of the cylindrical wave equation, respectively ( or vice versa, depending on the sign convention for the frequency ).
8.
The Hankel functions of the first and second kind are used to express outward-and inward-propagating cylindrical wave solutions of the cylindrical wave equation, respectively ( or vice versa, depending on the sign convention for the frequency ).

10.
This third version was retitled " On gravitational waves ", and, following Robertson's suggestion of a transformation to cylindrical coordinates, presented what are now called Einstein Rosen cylindrical waves ( these are locally isometric to plane waves ).
