FAST MULTISCALE GAUSSIAN WAVEPACKET TRANSFORMS AND MULTISCALE GAUSSIAN BEAMS FOR THE WAVE EQUATION
ast multiscale Gaussian wavepacket transforms multiscale Gaussian beams wave equations
2015/7/14
We introduce a new multiscale Gaussian beam method for the numerical solution of the wave equation with smooth variable coefficients. The first computational question addressed in this paper is how to...

Debye theory high numerical aperture elliptically polarized focusing
2013/7/2
Based on the vectorial Debye theory, the focusing properties of the Gaussian beam through an annular high numerical aperture are studied numerically, including the intensity, the phase and the orbital...
Laguerre-Gaussian Beams and Optical Orbital Angular Momentum
Laguerre-Gaussian beam Optical orbital angular momentum Angular momentum flux
2009/6/8
Laguerre-Gaussian beams are solutions of the paraxial wave equation and carry orbital angular momentum, which can be transferred to trapped particles. Orbital angular momentum of light beams can be be...
