A closer look at the spatial distribution of intensities reveals a fine structure with characteristic maxima and minima that cannot be predicted by a simple geometrical model and that depends on the complex interference of the

The comparison between the imprinted and calculated near field distribution shows an excellent agreement

Such near-field patterns, in strength as well as spatial distribution, are not obtainable upon linear polarized excitation
