Features of the gouy phase of nondiffracting beams
(E M W Publishing, 2013-06)
It is shown how the linear Gouy phase of an ideal nondiffracting beam of ±(k-kz)z form, with kz being the projection of the wavevector of modulus k of the plane wave spectrum onto the propagation axis z, is built from a ...
Integral localized approximation description of ordinary Bessel beams and application to optical trapping forces
(Optical Soc AmerWashingtonEUA, 2011)
Dual behavior of caustic optical beams facing obstacles
(American Physical Society, 2017-06)
A full propagation analysis on both fold-type and cusp-type caustic optical beams under various setups of obstructions is theoretically and experimentally performed. It is demonstrated that the self-healing property of ...
Caustic beams from unusual powers of the spectral phase
(Optical Society of America, 2017-10)
Caustic optical beams arising from a spectral phase whose power lies in an unusual range of values less than two are presented. Unlike what happens for conventional phase powers greater than two, it is feasible to generate ...
Free vibrations of AFG cantilever tapered beams carrying attached masses
The free transverse vibrations of axially functionally graded (AFG) cantilever beams with concentrated masses attached at different points are studied in this paper. The material properties of the AFG beam, consisting of ...
Symmetric airy beams
(Optical Society Of America, 2014-04)
In this Letter a new class of light beam arisen from the symmetrization of the spectral cubic phase of an Airy beam is presented. The symmetric Airy beam exhibits peculiar features. It propagates at initial stages with a ...
Intensity-symmetric Airy beams
(Optical Society of America, 2015-02)
Theoretical, numerical, and experimental research on a novel family of Airy beams in rectangular coordinates having a symmetric transverse pattern of light intensity is presented. The intensity-symmetric Airy beams include ...
Superposition of monochromatic Bessel beams in (k(p), k(z))-plane to obtain wave focusing: Spatial localized waves
(Elsevier Science BvAmsterdamHolanda, 2005)
Timoshenko theory effect on the vibration of axially functionally graded cantilever beams carrying concentrated masses
In this paper is studied the effect of considering the theory of Timoshenko in the vibration of AFG beams that support ground masses. As it is known, Timoshenko theory takes into account the shear deformation and the ...
Analysis of on-axis wave focusing through the use of non annular slits
