Résumé
The coupling between the surface plasmons of two overlapping arrays of orthogonally oriented subwavelength elliptical holes has been demonstrated by terahertz time-domain spectroscopy over the 0.1-1 THz range. This enhanced transmission exhibits polarization sensitive frequency shift. Three-dimensional numerical simulations provide precise insight in the energy redistribution of the surface plasmons through the subwavelength holes. A simple theoretical model, demonstrating a strong coupling between the two subarrays, exhibits good agreement with the experimental data.
