Uncovering the kiloparsec-scale stellar ring of NGC5128
J. T. Kainulainen, J. F. Alves, Y. Beletsky +8
We reveal the stellar light emerging from the kiloparsec-scale, ring-like structure of the NGC5128 (Centaurus A) galaxy in unprecedented detail. We use arcsecond-scale resolution n…
Towards a systematic design of isotropic bulk magnetic metamaterials using the cubic point groups of symmetry
J. D. Baena, L. Jelinek, R. Marques
In this paper a systematic approach to the design of bulk isotropic magnetic metamaterials is presented. The role of the symmetries of both the constitutive element and the lattice…
Neutron background signal in superheated droplet detectors of the Phase II SIMPLE dark matter search
A. C. Fernandes, A. Kling, M. Felizardo +7
The simulation of the neutron background for Phase II of the SIMPLE direct dark matter search experiment is fully reported with various improvements relative to previous estimates.…
Balanced right/left-handed mixtures of quasi-planar chiral inclusions
R. Marques, F. Mesa, L. Jelinek +1
Some novel quasi-planar chiral inclusions, feasible from standard photo-etching techniques, are proposed. It is shown that such inclusions can be designed in order to present balan…
Unified Homogenization Theory for Magnetoinductive and Electromagnetic Waves in Split Ring Metamaterials
J. D. Baena, L. Jelinek, R. Marques +1
A unified homogenization procedure for split ring metamaterials taking into account time and spatial dispersion is introduced. The procedure is based on two coupled systems of equa…
The SIMPLE Phase II Dark Matter Search
M. Felizardo, TA Girard, T. Morlat +13
Phase II of SIMPLE (Superheated Instrument for Massive ParticLe Experiments) searched for astroparticle dark matter using superheated liquid CClF droplet detectors. Eac…
Negative refraction from quasi-planar chiral inclusions
R. Marques, L. Jelinek, F. Mesa
This letter proposes a quasi-planar chiral resonator suitable for the design of negative refractive index matamaterial. It is presented an analytical model for the determination of…
Final Analysis and Results of the Phase II SIMPLE Dark Matter Search
M. Felizardo, T. A. Girard, T. Morlat +14
We report the final results of the Phase II SIMPLE measurements, comprising two run stages of 15 superheated droplet detectors each, the second stage including an improved neutron…
Metamaterial inspired perfect tunneling in semiconductor heterostructures
L. Jelinek, J. D. Baena, J. Voves +1
In this paper we are using formal analogy of electromagnetic wave equation and Schrodinger equation in order to study the phenomenon of perfect tunneling (tunneling with unitary tr…
Exact modeling method for discrete finite metamaterial lens
M. Lapine, L. Jelinek, R. Marques +1
We describe an efficient rigorous model suitable for calculating the properties of finite metamaterial samples, which takes into account the discrete structure of metamaterials bas…
Three dimensional super-resolution in metamaterial slab lenses
F. Mesa, R. Marques, M. Freire +1
This letter presents a theoretical and experimental study on the viability of obtaining three dimensional super-resolution (i.e. resolution overcoming the diffraction limit for all…
Negative refraction in (bi)-isotropic periodic arrangements of chiral SRRs
L. Jelinek, R. Marques, F. Mesa +1
Bi-isotropic and isotropic negative refractive index (NRI) 3D metamaterials made from periodic arrangements of chiral split ring resonators (SRRs) are proposed and demonstrated. An…
Artificial magnetism and left handed media from dielectric rings and rods
L. Jelinek, R. Marques
It is shown that artificial magnetism with relatively large frequency bandwidth can be obtained from periodic arrangements of dielectric rings. Combined with dielectric rods, diele…
G0.253+0.016: a molecular cloud progenitor of an Arches-like cluster
Steven N. Longmore, Jill Rathborne, Nate Bastian +20
Young massive clusters (YMCs) with stellar masses of 10^4 - 10^5 Msun and core stellar densities of 10^4 - 10^5 stars per cubic pc are thought to be the `missing link' between open…
Strong spatial dispersion in wire media in the very large wavelength limit
P. A. Belov, R. Marques, S. I. Maslovski +4
It is found that there exist composite media that exhibit strong spatial dispersion even in the very large wavelength limit. This follows from the study of lattices of ideally cond…
Radius-mass scaling laws for celestial bodies
R. Muradian, S. Carneiro, R. Marques
In this letter we establish a connection between two-exponent radius-mass power laws for cosmic objects and previously proposed two-exponent Regge-like spin-mass relations. A new,…
