Peculiarities of excitation of surface plasmons upon noncollinear light scattering

Numerical investigation of the excitation of surface plasmon polariton on a periodic surface nanograting composed of metallic nanowires

“…The solution of the vector's Maxwell's equations provides the expressions for the partial reflection and transmission coefficient of a separate inhomogeneous layer. Note, that th is ap proach was used in [19][20][21] to calcu late th e in tensity o f bo th lin ear and non linear op tical respo nse of p eriodic metallic diffraction gratings as a function of (i) the light angle, wavelength, and (ii) polarization of the incident wave, as well as o f (iii) th e ro tation an gle of t he g rating arou nd its normal. Th e calcu lation results agree well with the experimental data.…”

“…Th e calcu lation results agree well with the experimental data.

Resonance Absorption of Light By Subwavelength Diffractive Gratings

“…The light excites surface plasmons through a grating [23]. The excitation of surface plasmons upon noncollinear scattering on a metallic diffraction grating was studied in [3]. In [4], it is shown that the resonance features in the spectral-angular dependencies of transmittance of nano-gratings are due to the excitation of surface plasmons at metal-air and metal-dielectric boundaries.…”

“…The interest in subwavelength gratings is growing due to their promising applications in high performance transmission and reflection filters [1], optoelectronic devices using surface plasmons [2][3][4], spectral-selective external optical mirrors for lasers (VCSELs) [5]. Subwavelength gratings have also been proposed for focusing light in the far [6], and near zones [7].…”
