Transformation Optics Using Graphene
TLDR
By designing and manipulating spatially inhomogeneous, nonuniform conductivity patterns across a flake of graphene, one can have this material as a one-atom-thick platform for infrared metamaterials and transformation optical devices.

TLDR
Here it is seen how a proper design of these lossless metamaterial covers near their plasma resonance may induce a dramatic drop in the scattering cross section, making these objects nearly "invisible" or "transparent" to an outside observer--a phenomenon with obvious applications for low-observability and noninvasive probe design.
Metamaterials: Physics and Engineering Explorations
Preface. Contributors. PART I: DOUBLE-NEGATIVE (DNG) METAMATERIALS. SECTION I: THREE-DIMENSIONAL VOLUMETRIC DNG METAMATERIALS. CHAPTER 1: INTRODUCTION, HISTORY, AND SELECTED TOPICS IN FUNDAMENTAL…
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 of…
Fractional curl operator in electromagnetics
The concept of fractional curl operator is introduced, and as one of its roles, it is briefly shown that the duality principle in electromagnetism for the source-free case can be fractionalized. ©…
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 while…

We present and analyze theoretically some ideas for thin one-dimensional (1D) cavity resonators in which a combination of a conventional dielectric material and a metamaterial possessing negative…
Circuit elements at optical frequencies: nanoinductors, nanocapacitors, and nanoresistors.
TLDR
Three basic circuit elements, i.e., nanoinductors, nanocapacitors, and nanoresistors, are discussed in terms of small nanostructures with different material properties, which may provide road maps for the synthesis of more complex circuits in the IR and visible bands.
Kinetics of Recovery of the Dark-adapted Salamander Rod Photoresponse
TLDR
Analysis of the kinetics of the dark-adapted salamander rod photocurrent response to flashes producing from 10 to 105 photoisomerizations yields an estimate of the calcium buffering capacity of the rod at rest of ∼20, much lower than previous estimates.
Tunneling of electromagnetic energy through subwavelength channels and bends using epsilon-near-zero materials.
TLDR
It is demonstrated theoretically that electromagnetic waves can be "squeezed" and tunneled through very narrow channels filled with epsilon-near-zero (ENZ) materials and it is discussed that in some cases the isotropy of the ENZ material may not be an issue.
