    Abstract

    The near-field enhancement in the sub-skin-depth regime fundamentally differs from the extraordinary optical transmission. We propose a simple model for explanation of the THz field enhancement in the metal slit in the sub-skin-depth regime. In our opinion the enhanced field is generated by the charges at the edges of the slit and therefore can be easily estimated. Conclusions of the model provide nice coincidence with the published experimental data.
