Abstract

The efficient electric field enhancement due to coating a dielectric wedge by plasmon-carrying nanowires has been demonstrated numerically within the framework of the finite-difference frequency-domain method. The numerical simulations show increasing of electric field intensity in the near-field region of the dielectric wedge coated by silver nanowires in the regime of local plasmon excitation up to 100 times versus the uncoated case.
