Spectrally stable thermal emitters enabled by material-based high-impedance surfaces
Radiative thermal engineering with subwavelength metallic bodies is a key element for heat and energy management applications, communication and sensing. Here, we numerically and experimentally demonstrate metallic thermal ... -
A splitting uniformly convergent method for one-dimensional parabolic singularly perturbed convection-diffusion systems
In this paper we deal with solving robustly and efficiently one-dimensional linear parabolic singularly perturbed systems of convection-diffusion type, where the diffusion parameters can be different at each equation and ... -
Stabilization of a clay soil using cementing material from spent refractories and ground-granulated blast furnace slag
Nowadays, huge amounts of refractory materials are generated around the world. The majority of them lack valorization methods. This study analyzes the ability of a doloma and two magnesia spent refractory wastes as soil ... -
Stable multi-wavelength fiber lasers for temperature measurements using an optical loop mirror
In this work, two novel stable multi-wavelength fiber laser configurations are proposed and demonstrated by using a spool of single-mode fiber as optical loop mirror and one or two fiber ring cavities, respectively. The ... -
State of health estimation of second-life lithium-ion batteries under real profile operation
The economic viability of second-life (SL) Li-ion batteries from electric vehicles (EVs) is still uncertain nowadays. Assessing the internal state of reused cells is key not only at the repurposing stage but also during ... -
Steering surface plasmons with a graded index dielectric medium
The arbitrary control of surface plasmon (SP) propagation has become an intense research topic for several decades. This is due to the fact that they can be used in a variety of fields such as optical trapping, nanoantennas ... -
Straightforward nano patterning on optical fiber for sensors development
A simple method to prepare a nano pattern along the surface of an optical fiber is applied in this Letter to develop a pH sensor. The template is made of a block copolymer that defines specific locations where gold nano ... -
Strain sensing based on resonant states in 2D dielectric photonic quasicrystals
This paper reports the numerical and experimental study of the strain sensing effect of bidimensional quasiperiodic structures made with dielectric cylinders. Structures of around 100 cylinders arranged following a Penrose ... -
Strengthened ordered directionally monotone functions. Links between the different notions of monotonicity
In this work, we propose a new notion of monotonicity: strengthened ordered directional monotonicity. This generalization of monotonicity is based on directional monotonicity and ordered directional monotonicity, two recent ... -
Stripline multilayer devices based on Complementary Split Ring Resonators
A new analytic design for multilayer stripline devices in planar circuit technology is presented. The Complementary Split Ring Resonator (CSRR) is used as a sub-wavelength resonant particle, which provides high-Q resonances ... -
Strong angular dependence of resonant states in 2D dielectric cylinder rings
We investigate collective resonators made of dielectric cylinders assembled as two-dimensional regular octagons and decagons. These structures exhibit collective resonance states that change their intensity with the incident ... -
Study of optical fiber sensors for cryogenic temperature measurements
In this work, the performance of five different fiber optic sensors at cryogenic temperatures has been analyzed. A photonic crystal fiber Fabry-Pérot interferometer, two Sagnac interferometers, a commercial fiber Bragg ... -
A study of OWA operators learned in convolutional neural networks
Ordered Weighted Averaging (OWA) operators have been integrated in Convolutional Neural Networks (CNNs) for image classification through the OWA layer. This layer lets the CNN integrate global information about the image ... -
Study on on-chip antenna design based on metamaterial-inspired and substrate-integrated waveguide properties for millimetre-wave and THz integrated-circuit applications
This paper presents the results of a study on improving the performance parameters such as the impedance bandwidth, radiation gain and efficiency, as well as suppressing substrate loss of an innovative antenna for on-chip ... -
Sub-synchronous resonance damping control strategy for DFIG wind turbines
Doubly-fed induction generator (DFIG) wind turbines connected to capacitive series-compensated transmission lines are prone to exhibit oscillatory behavior. The phenomena is called sub-synchronous resonances (SSRs), as ... -
Subsampling OFDM-based ultrasonic data communication through metallic channels for monitoring of cargo containers
An enhanced ultrasonic communication system based on piezoelectric transducers for monitoring of goods in cargo containers is presented. The proposed system consists of several sensors placed inside the container, whose ... -
Sulphate soil stabilisation with magnesium binders for road subgrade construction
This paper analyzes the ability of magnesium oxide-based additives to stabilise a low bearing gypsum marly soil, in order to reach subgrade requirements. This soil was not adequate for stabilisation with lime or cement ... -
