An Ewald decomposition of the two-dimensional Yukawa potential and itsderivative is presented for both the periodic and the free-space case. Thesemodified Bessel functions of the second kind of zeroth and first degrees areused e.g. when solving the modified Helmholtz equation using a boundaryintegral method. The spectral Ewald method is used to compute arising sums atO(N log N) cost for N source and target points. To facilitate parameterselection, truncation-error estimates are developed for both the real-space sumand the Fourier-space sum, and are shown to estimate the errors well.
