  • Abstract
    An array of sub-wavelength circular apertures (d=60 mum), periodically distributed in a square lattice, was studied in the near field using Terahertz Time-Domain Spectroscopy (THz-TDS). Images of the complete electric field distribution (Emacrx,Emacry,Emacrz) were recorded over a subsection of the array, as well as the corresponding spectral information, with a spatial resolution Lt10 mum.
