The fast multipole method (FMM) for electromagnetic scattering problems
The fast multipole method (FMM) developed by V. Rokhlin (1990) to efficiently solve acoustic scattering problems is modified and adapted to the second-kind-integral-equation formulation ofExpand

Pairing an epsilon-negative slab with a mu-negative slab: resonance, tunneling and transparency
Here, we analyze the transverse-magnetic (TM) wave interaction with a pair of slabs, one being an epsilon-negative (ENG) layer in which the real part of permittivity is assumed to be negative whileExpand

Circuit elements at optical frequencies: nanoinductors, nanocapacitors, and nanoresistors.
We present the concept of circuit nanoelements in the optical domain using plasmonic and nonplasmonic nanoparticles. Three basic circuit elements, i.e., nanoinductors, nanocapacitors, andExpand

Tunneling of electromagnetic energy through subwavelength channels and bends using epsilon-near-zero materials.
In this Letter, we demonstrate theoretically that electromagnetic waves can be "squeezed" and tunneled through very narrow channels filled with epsilon-near-zero (ENZ) materials. We show that theExpand
