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 ...
Superposition of monochromatic Bessel beams in (k(p), k(z))-plane to obtain wave focusing: Spatial localized waves
(Elsevier Science BvAmsterdamHolanda, 2005)
Analysis of on-axis wave focusing through the use of non annular slits
(Elsevier Science BvAmsterdamHolanda, 2004)
Timoshenko versus Euler beam theory: Pitfalls of a deterministic approach
(ELSEVIER SCIENCE BV, 2011)
The selection criteria for Euler-Bernoulli or Timoshenko beam theories are generally given by means of some deterministic rule involving beam dimensions. The Euler-Bernoulli beam theory is used to model the behavior of ...
General formulation for the analysis of scalar diffraction-free beams using angular modulation: Mathieu and Bessel beams
(Elsevier Science BvAmsterdamHolanda, 2003)
Discrete modeling and experimental validation of the model of a cantilever flexible beam
(2015-04-01)
Cantilevered beams are studied in many ways because they are simple and largely applicable in many engineering problems. This study shows the development of a discrete dynamic model for a flexible cantilever beam and the ...
Influence of nonlinear stiffness on the dynamics of a slender elastic beam under torsional oscillations
(2014)
This study focuses on analysing the effects of nonlinear torsional stiffness on the dynam-ics of a slender elastic beam under torsional oscillations, which can be subject to helical buckling.The helical buckling of an ...
