Hankel Function -- from Wolfram MathWorld
WebHankel function order, specified as a symbolic array or double array. If nu and z are arrays of the same size, the result is also that size. If either input is a scalar, besselh expands it … The Hankel functions are used to express outward- and inward-propagating cylindrical-wave solutions of the cylindrical wave equation, respectively (or vice versa, depending on the sign convention for the frequency ). Using the previous relationships, they can be expressed as If α is an integer, the limit … 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 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 … See more For integer order α = n, Jn is often defined via a Laurent series for a generating function: A series expansion using Bessel functions (Kapteyn series) is Another important … See more Bourget's hypothesis Bessel himself originally proved that for nonnegative integers n, the equation Jn(x) = 0 has an infinite number of solutions in x. When the functions Jn(x) are plotted on the same graph, though, none of the zeros seem to coincide … See more Because this is a second-order linear differential equation, there must be two linearly independent solutions. Depending upon the circumstances, however, various formulations of … See more The Bessel functions have the following asymptotic forms. For small arguments $${\displaystyle 0 WebThe Hankel functions are known to our symbolic computing systems as HankelH1 (n,x) and HankelH2 (n,x) ( maple) HankelH1 [n,x] and HankelH2 [n,x] ( mathematica) Sample … incarcator wireless s6
