Since this translational operator is now in terms of parameters *v* and
which are constant across layer boundaries, we can form the
*n*-layer transformation by forming the product of the *n* individual
layer transformations. In the case of the first three terms of our
truncated power series approximation of Equation 8,
this leads to
