(possibly multilayered) spherical particles of arbitrary size and electric permeability. Within …

Young's experiment with a double slit of sub-wavelength dimensions

K Lee, J Lim, J Ahn - Optics Express, 2013 - opg.optica.org
We report that the interference pattern of Young's double-slit experiment changes as a
function of polarization in the sub-wavelength diffraction regime. Experiments carried out …

Terahertz polarization spectroscopy in the near-field zone of a sub-wavelength-scale metal slit
