PPT-Bessel Functions   Bessel functions

are   canonical  solutions  y x of  Bessels  differential equation α the  order  of the Bessel function Bessel functions are also known as  cylinder functions  or . we have that is a second solution of the di64256erential equation 2 and the two solutions and are clearly linearly independent For 8712 we have 0 1 915 1 1 915 1 since 915 1 0 for 0 n This implies that 1 915 1 0 1 915 1 2 1 0 1 91 They are im portant in math as well as in physical sciences physics and engineering They are especially important in solving boundary values problems in cylindrical coordi nates First we de57356ne another important function the Gamma function which intelcom Abstract The Bessel functions are considered relatively dif64257cult to compute Although they have a simple power series expan sion that is everywhere convergent they exhibit approxi mately periodic behavior which makes the direct use of the 02 501 V 75V V IN 2V RMS Operates with a Single 5V Supply 1V RMS Input Range 60 RMS Clock Feedthrough Single 5V Supply Operates up to 8V Supplies TTLCMOSCompatible Clock Input No External Components Available in 14Pin DIP and 16Pin SO Wide Packages 02 501 V 75V V IN 2V RMS Operates with a Single 5V Supply 1V RMS Input Range 60 RMS Clock Feedthrough Single 5V Supply Operates up to 8V Supplies TTLCMOSCompatible Clock Input No External Components Available in 14Pin DIP and 16Pin SO Wide Packages : .

Thus, we must quantify our Bessel beam using a fitting algorithm. There is no already made one so it must coded. Co-Authors: Joshua Nelson, Adam Summers, Dr. Carlos Trallero and Dr. Bret Flanders.
