A water content continuous monitoring of grapevine xylem tissue using a portable low-power cost-effective FMCW radar
This paper presents the real-time monitoring of a grapevine’s water content that flows up through the xylem tissue by means of a frequency-modulated continuous-wave (FMCW) radar. The application of an optimization process, ... -
Watt-level green random laser at 532 nm by SHG of Yb-doped fiber laser
We have developed a Watt-level random laser at 532 nm. The laser is based on a 1064 nm random distributed ytterbium-gain assisted fiber laser seed with a 0.35 nm line-width and 900 mW polarized output power. A study for ... -
Wavelength and intensity based lossy mode resonance breathing sensor
Copper oxide (CuO) allows the generation of lossy mode resonance (LMR) in a wide wavelength range of the optical spectrum, both in the visible and the near-infrared (NIR). For this, it is necessary to use a configuration ... -
Wavelength converter using a highly Er-doped optical fiber ring laser
This work presents an all-fiber wavelength converter based on a highly Er-doped fiber laser, which has been experimentally demonstrated. Frequencies from several kilohertz up to tens of gigahertz have been investigated. ... -
Wavelength-switchable L-band fiber laser assisted by random reflectors
A wavelength-switchable L-band erbium-doped fiber laser (EDFL) assisted by an artificially controlled backscattering (ACB) fiber reflector is here presented. This random reflector was inscribed by femtosecond (fs) laser ... -
Winding resistance measurement in power inductors - understanding the impact of the winding mutual resistance
Inductors are cornerstone components in power electronics converters. Since winding loss is the dominant loss mechanism in these components, its accurate measurement is fundamental for the validation of the inductor's ... -
Wireless characterization and assessment of an UWB-Based system in industrial environments
The advent of Indsutrial Internet of Things is one of the main drivers for the implementation of Industry 4.0 scenarios and applications, in which wireless communication systems play a key role in terms of flexibility, ... -
Zero-loss switching in LLC resonant converters under discontinuous conduction mode: analysis and design methodology
Many thriving applications where isolation is required, such as LED drivers, traction and EV fast charging, implement LLC resonant converters, particularly when voltage regulation is not required or an additional ...
