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 ... -
Substrate-integrated photonic doping for near-zero-index devices
Near-zero-index (NZI) media, a medium with near zero permittivity and/or permeability, exhibits unique wave phenomena and exciting potential for multiple applications. However, previous proof-of-concept realizations of NZI ... -
Super class AB RFC OTA with adaptive local common-mode feedback
A super class AB recycling folded cascode operational transconductance amplifier is presented. It employs local common-mode feedback using two matched tuneable active resistors, allowing to adapt the amplifier to different ... -
Super-gain-boosted AB-AB fully differential Miller op-amp with 156dB open-loop gain and 174MV/V MHZ pF/uW figure of merit in 130nm CMOS technology
A fully differential Miller op-amp with a composite input stage using resistive local common-mode feedback and regulated cascode transistors is presented here. High gain pseudo-differential auxiliary amplifiers are used ... -
Super-wide impedance bandwidth planar antenna for microwave and millimeter-wave applications
A feasibility study of a novel configuration for a super-wide impedance planar antenna is presented based on a 2 × 2 microstrip patch antenna (MPA) using CST Microwave Studio. The antenna comprises a symmetrical arrangement ... -
Supercapacitors: electrical characteristics, modelling, applications and future trends
Energy storage systems are playing an increasingly important role in a variety of applications, such as electric vehicles or grid-connected systems. In this context, supercapacitors (SCs) are gaining ground due to their ... -
Suppressed-scattering spectral windows for radiative cooling applications
The scattering of light by resonant nanoparticles is a key process for enhancing the solar reflectance in daylight radiative cooling. Here, we investigate the impact of material dispersion on the scattering performance of ... -
Surface exciton polariton resonances (SEPR)-based sensors
(Elsevier, 2023) Artículo / ArtikuluaA new type of resonance in the development of sensors using long-range surface exciton polariton (LRSEP) phenomena has been coined: surface exciton plasmon resonance (SEPR). The resonance was obtained in the reflected ... -
Surface wave reduction in antenna arrays using metasurface inclusion for MIMO and SAR systems
An effective method is presented for suppressing mutual coupling between adjacent radiating elements which is based on metasurface isolation for multiple-input multiple-output (MIMO) and synthetic aperture radar (SAR) ... -
A survey on detection techniques for cryptographic ransomware
Crypto-ransomware is a type of malware that encrypts user files, deletes the original data, and asks for a ransom to recover the hijacked documents. It is a cyber threat that targets both companies and residential users, ... -
Synplex: in silico modeling of the tumor microenvironment from multiplex images
Multiplex immunofluorescence is a novel, high-content imaging technique that allows simultaneous in situ labeling of multiple tissue antigens. This technique is of growing relevance in the study of the tumor microenvironment, ... -
Synthesis of rectangular waveguide filters with smooth profile oriented to direct metal additive manufacturing
In this paper, a novel design method for rectangular waveguide filters intended for fabrication using direct metal additive manufacturing is proposed. The synthesized filters will feature a smooth profile that allows us ... -
Telecommunications on Earth and their possible relation with the anthropic principle
The society of the information is based on the ability of humans to communicate in real time. This is possible thanks to the emission of electromagnetic waves. In this work it is discussed, by analyzing the round trip time ... -
Tenderness of PGI "Ternera de Navarra" beef samples determined by FTIR-MIR spectroscopy
Understanding meat quality attribute changes during ageing by using non-destructive techniques is an emergent pursuit in the agroindustry research field. Using beef certified samples from the protected geographical indication ... -
Thermoelectric generator with passive biphasic thermosyphon heat exchanger for waste heat recovery: design and experimentation
One of the measures to fight against the current energy situation and reduce the energy consumption at an industrial process is to recover waste heat and transform it into electric power. Thermoelectric generators can be ... -
