Cylindrical bessel functions
WebWe numerically demonstrate that the tight focusing of Bessel beams can generate focal fields with ultra-long depth of focus (DOF). It is found that the ultra-long focal field can be controlled by appropriately regulating the order of Bessel function and the polarization. Optical needle and optical dark channel with nearly 100 DOF are generated. http://nsmn1.uh.edu/hunger/class/fall_2013/lectures/lecture_8.pdf

WebThe first is to directly simulate the coupling mechanisms of the unsteady flow, combustion, and acoustic dynamics based on the complete three-dimensional compressible Computational Fluid Dynamics (CFD) simulations;the compressible large eddy simulation (LES) is typically preferred among these CFD solvers [ 5, 7 ]. Bessel functions for integer are also known as cylinder functions or the cylindrical harmonics because they appear in the solution to Laplace's equation in cylindrical coordinates. Spherical Bessel functions with half-integer are obtained when the Helmholtz equation is solved in spherical coordinates .
