In nanophotonics, dielectric lenses are used for in-plane focusing of surface plasmon modes, but there is no control over the diffracted fields and focal length of the lens after it has been fabricated. We introduce a conceptual dielectric lens...

In this paper, a device for coupling light into symmetric and asymmetric surface plasmon modes in a metallic thin film is presented. This device consists of a two-dimensional periodic array of nanoparticles located above a silver thin film...

A dielectric lens placed on a metal-dielectric interface can be used for in-plane focusing of surface plasmon (SP) modes. Here, we have used vectorial derivation of Huygens-Fresnel principal to calculate the diffracted fields behind the lens...

Using the vectorial form of the Huygen-Fresnel principle, we have studied the diffraction of a surface plasmon mode propagating on a metal-dielectric interface as it passes through a dielectric thick lens. This method, unlike the scalar diffraction...

We have investigated the propagation of a surface plasmon mode on a metal-dielectric interface with a discontinuity. Our rigorous study of the boundary conditions illustrates a mismatch between the normal components of the wavevectors...

In this paper, we investigate the characteristics of a new device for coupling light into symmetric/asymmetric surface plasmon modes on each side of a metallic thin film....

Optical cross-section of individual metallic nanoparticles in dielectric-loaded media have been studied to efficiently propose electric-field enhancement schemes in nanophotonic networks and devices.
