Adaptive perfectly matched layer for Wood's anomalies in diffraction gratings
Benjamin Vial, Frédric Zolla, André Nicolet +2
We propose an Adaptive Perfectly Matched Layer (APML) to be used in diffraction grating modeling. With a properly tailored co-ordinate stretching depending both on the incident fie…

Transmission enhancement through square coaxial apertures arrays in metallic film: when leaky modes filter infrared light
Benjamin Vial, Frédéric Bedu, Hervé Dallaporta +6
We consider arrays of square coaxial apertures in a gold layer and study their diffractive behavior in the far infrared region. These structures exhibit a resonant transmission enh…
