Ultrahigh sensitive detection of tau protein as Alzheimer's biomarker via microfluidics and nanofunctionalized optical fiber sensors
Alzheimer’s disease (AD) is one of the most common neurodegenerative illnesses displaying the highest death rate in the elderly. However, the existing AD diagnostic system remains elusive due to lack of a technology that ... -
Optomagnonics in dispersive media: magnon-photon coupling enhancement at the epsilon-near-zero frequency
Reaching strong light-matter coupling in solid-state systems has long been pursued for the implementation of scalable quantum devices. Here, we put forward a system based on a magnetized epsilon-near-zero (ENZ) medium, and ... -
Enhancing the infrared and visible emission properties of calcium silicate hydrate for radiative cooling using metamaterials
Two periodic structures composed of metal cylinders with different orientations are used to improve the solar reflection of calcium silicate hydrate (CSH) while maintaining its atmospheric emission. Interesting effects ... -
Design of multi-layered radiative cooling structures using evolutionary algorithms
In this work we present a novel way to design thinfilm radiative cooling metamaterials based on genetic algorithms. Three simulations with different design constraints have been done, resulting in three structures that ... -
Double-port slotted-antenna with multiple miniaturized radiators for wideband wireless communication systems and portable devices
Proof-of-concept is presented of a novel slot antenna structure with two excitation ports. Although this antenna provides a wide impedance bandwidth, its peak gain and optimum radiation efficiency are observed at its ... -
Methodology for sizing stand-alone hybrid systems: a case study of a traffic control system
This paper proposes a methodology for sizing stand-alone hybrid photovoltaic-wind power generation systems. This methodology makes it possible to optimise the overall performance of the stand-alone system components, based ... -
Routing with classical corrugated waveguide low-pass filters with embedded bends
A very simple design method to embed routing capabilities in classical corrugated filters is presented in this paper. The method is based on the calculation of the heights and lengths of the so-called filters design ... -
Luminescence-based optical fiber oxygen sensors fabricated by means of layer-by-layer nano-assembly
Over the last decades, luminescence quenching has been established as a widespread technique for gaseous oxygen monitoring in a broad range of applications. Thus, considerable effort has been made to manufacture luminescent ... -
Comparison between capacitive and microstructured optical fiber soil moisture sensors
Soil moisture content has always been an important parameter to control because it is a deterministic factor for site-specific irrigation, seeding, transplanting, and compaction detection. In this work, a discrete sensor ... -
