In the rigorous electromagnetic simulation of an imaging system, the evanescent waves from a point source or from a sample are naturally mixed with the propagative waves. Therefore, their contributions are difficult to distinguish. We present a point-source model made of only the evanescent waves. To illustrate its potential, the model is applied to the study of the evanescent-wave contribution in microsphere-assisted microscopy (MAM).
