Compared to the other acceleration techniques, Ewald method converges fastest (Gaussian convergence) and is the most accurate when the observation point gets close to the sources.
However, the Ewald method successfully combines both formulations into fast converging series.
This shows research in the design of nonlinear optical materials through various theoretical techniques, such as first-principle approaches and the Ewald method.
