Abstract :
A method is presented for calculating the wake potential of a bunched beam of arbitrary charge distribution, directly from the wake potential of a shorter bunch, by using orthogonal polynomial expansions. Combined with the table-look-up technique, this method leads to an effective computation scheme for repetitive evaluation of wake potentials of different charge distributions under the same boundary conditions.<>
