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. Webcylindrical geometry leads a singular Sturm-Liouville with the parametric Bessel’s equation which in turn allows solutions to be represented as series involving Bessel functions. 1. …
WebMar 24, 2024 · The cylinder function is defined as C(x,y)={1 for sqrt(x^2+y^2)<=a; 0 for sqrt(x^2+y^2)>a. (1) The Bessel functions are sometimes also called cylinder functions. To find the Fourier transform …
The Bessel function is a generalization of the sine function. It can be interpreted as the vibration of a string with variable thickness, variable tension (or both conditions simultaneously); vibrations in a medium with variable properties; vibrations of the disc membrane, etc. Bessel's equation arises when finding separable … See more Bessel functions, first defined by the mathematician Daniel Bernoulli and then generalized by Friedrich Bessel, are canonical solutions y(x) of Bessel's differential equation The most important … See more Because this is a second-order linear differential equation, there must be two linearly independent solutions.
