WebBESSEL FUNCTIONS AND THE HANKEL TRANSFORM 2.1 P. ROPERTIES OF THE. B. ESSEL FUNCTIONS. In order to discuss Bessel functions, we must first discuss the Gamma function. The Gamma function is defined as the following integral [6] G(r)= Z ¥ 0. e. t. t. r 1. dt r >0: (2.1) We can consider it to be related to the factorial function because … WebTherefore, for the time-harmonic fields of e jvt, the Hankel function of the first kind represents a wave propagating in the 2x direction, whereas the Hankel function of the second kind represents a wave propagating in the þx direction. The recurrence relations for the Bessel function are as follows: J n 1(x) þ J nþ1(x) ¼ 2n x J n(x), (C ...
