Abstract

A method of evaluation of lattice Green functions using a Fourier series expansion of their imaginary parts is developed. It is shown, through an example, that numerical evaluation of the real and imaginary parts of the Green functions can be done by this method with much greater ease than by direct integration of the Green function integrals, with the added advantage that the real and imaginary parts of the Green functions can be represented by simple analytic expressions with good approximation.
