Achieving transparency with plasmonic and metamaterial coatings.
The possibility of using plasmonic and metamaterial covers to drastically reduce the total scattering cross section of spherical and cylindrical objects is discussed. While it is intuitively expected… Expand
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… Expand
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, and… Expand
Full control of nanoscale optical transmission with a composite metascreen.
By applying the optical nanocircuit concepts to metasurfaces, we propose an effective route to locally control light transmission over a deeply subwavelength scale. This concept realizes the optical… Expand
First-principles homogenization theory for periodic metamaterials
- A. Alú
- 6 December 2010
We derive from first principles an accurate homogenized description of periodic metamaterials made of magnetodielectric inclusions, highlighting and overcoming relevant limitations of standard… Expand
Magnetless Microwave Circulators Based on Spatiotemporally Modulated Rings of Coupled Resonators
Nonreciprocal components are ubiquitous in electronic and optical systems. To date, the use of magneto-optical materials has been the prevailing method to achieve nonreciprocity. However,… Expand
Polarizabilities and effective parameters for collections of spherical nanoparticles formed by pairs of concentric double-negative, single-negative, and∕or double-positive metamaterial layers
Unusual scattering effects from tiny spherical particles may be obtained when concentric shells are designed by pairing together “complementary” double-negative, single-negative, and∕or standard… Expand
Sound Isolation and Giant Linear Nonreciprocity in a Compact Acoustic Circulator
Acoustically Isolated The control of sound transmission is desirable in a number of circumstances from noise suppression to imaging technologies. Fleury et al. (p. 516; see the cover; see the… Expand
Magnetic-free non-reciprocity and isolation based on parametrically modulated coupled-resonator loops
Communication systems require non-reciprocal electromagnetic propagation, which is difficult to realize in circuits. An alternative is demonstrated by modulating the phase of strongly coupled… Expand
Twisted optical metamaterials for planarized ultrathin broadband circular polarizers.
Optical metamaterials are usually based on planarized, complex-shaped, resonant nano-inclusions. Three-dimensional geometries may provide a wider set of functionalities, including broadband chirality… Expand
