      and experimental modeling.

AB  - The development of acoustic source technology has been an important task for
      acoustic logging while drilling (LWD) and various source designs have been
      implemented. Using a multipole wave expansion theory, this study demonstrates
      that a LWD acoustic source can be represented as a combination of monopole,
      dipole, and quadrupole constituents and characterized by the contribution of each
      constituent. The theoretical analysis is experimentally demonstrated with a
      cylindrical pipe simulating the LWD collar. The result of this study can be used 
      to provide a method for evaluating the performance of a LWD acoustic source.
