A broadband high-gain single-feed cross-aperture coupled patch antenna is presented in this paper. The measured results confirm that the antenna is capable of a 14.4% impedance bandwidth (VSWR 2), 3% of 3-dB axial-ratio ...
The temporal evolution of the alpha-factor during pump-probe experiments in semiconductor optical amplifiers (SOAs) is not constant but varies strongly with time. It even takes on negative values for short periods of time. ...
Tensor rank refers to the number of product states needed to express a given multipartite quantum state. Its nonadditivity as an entanglement measure has recently been observed. In this Brief Report, we estimate the tensor ...
Using a newly developed gold Embedded Atom Model potential we conducted molecular dynamics simulations of inert gas aggregation type nanoparticle growth to investigate morphology transformations during the growth process. ...
Magnetization measurements at 10 K on the dc demagnetized ferromagnetic intermetallic compounds Nd-3(Fe,Ti)(29) and Nd-3(Fe,Re)(29) are reported and reveal the phenomena of thermal and spontaneous remagnetization. For both ...
In this paper we consider a stationary thermodynamic system that includes a transformer of mechanical energy into heat energy or heat into mechanical energy. We derive conditions that determine temperature distribution ...
The influence of surface barrier on the third harmonics ac susceptibility (chi(3)) is studied numerically. The surface barrier is described by a critical current density in surfaces which are higher than the inside one. ...
The Monte Carlo software CASINO has been expanded with new modules for the simulation of complex beam scanning patterns, for the simulation of cathodoluminescence (CL), and for the calculation of electron energy deposition ...
A three-dimensional (3-D) magnetic property measurement system, which can control the three components of the magnetic flux density B vector and measure the magnetic field strength H vector in a cubic sample of soft magnetic ...
This paper investigates the thrust forces of two novel permanent magnet transverse flux linear oscillating actuators (TFLOAs), one with moving magnet and the other moving both magnet and iron core, for pump and compressor ...
Torsional finite elements for direct, branched and grounded (boundary) connections and geared connections with rigid or elastic tooth mesh are presented. The use of these elements for developing dynamic models of various ...
We demonstrate that multiple copies of a bipartite entangled pure state may serve as a catalyst for certain entanglement transformations while a single copy cannot. Such a state is termed a
Comprehensive theoretical and numerical studies of the effects of dispersion and absorption on the Anderson localization of classical waves in weakly disordered, one-dimensional stacks composed of dispersive metamaterials ...
In-plane bandgap energy control of InAs quantum dots (QDs) grown on GaAs substrates is demonstrated using selective-area epitaxy. Transmission electron microscopy and cathodoluminescence are used for characterization of ...

Using the exact theory of multipole expansions, we construct the two-dimensional Green’s function for
photonic crystals, consisting of a finite number of circular cylinders of infinite length. From this Green’s
function, ...
The fabrication of stable ultrabright single photon sources operating at room temperature Is reported. The emitter is based on a color center within a diamond nanocrystal grown on a sapphire substrate by chemical vapor ...
We present results of photoluminescence and cathddoluminescence measurements of strained undoped In0.15Ga0.85AsGaAs and In0.15Ga0.85AsAl0.15Ga0.85As quantum well structures, designed to throw light on the current controversy ...
