Optical nanocouplers matching a fiber microwaveguide to a plasmonic nanowaveguide are essential components for practical applications of nanophotonic systems. In this Letter we design an efficient nanocoupler using a directive nanoantenna in the visible range Î»0=0.65 Î¼m. The antenna has been optimized both in the configuration and in the matching element inâ€¦ (More)

The majority of the surface integral equation (SIE) formulations have balancing problems due to the very different scales of the equivalent electric and magnetic currents. As a result of this, the impedance matrix usually has an ill-condition number because of the imbalance between the different blocks, and the use of a preconditioner for a correctâ€¦ (More)

The aim of this work is to present efficient surface-integral-equation techniques based on the method of moments and fast solvers for the electromagnetic solution of composite conducting and penetrable objects.

In this work we present efficient solutions of Surface Integral Equations to solve electromagnetic problems in nanophotonics. These efficient solutions are based on arranging equations to be valid for plasmonic and other exotic materials. Solutions to these problems provide efficient solutions to new leading-edge applications, including analysis of newâ€¦ (More)

Surface integral equation (SIE) formulations such as PMCHWT, Müller, CTF, CNF, or JMCFIE, suffer from balancing problems with respect to electric and magnetic currents or with coupling between them. Method of Moments (MoM) discretization of these surface integral equations suffers from high- or ill- condition number due to this unbalancing betweenâ€¦ (More)
