Comparison of fourth-harmonic and combined doubler/subharmonic mixer with integrated MMIC based local oscillator
In this paper a comparison between a fourth harmonic mixer and a combined doubler/subharmonic mixer based on Schottky diodes working at 300 GHz with MMIC Local Oscillator (LO) integrated in a single enclosing is presented. ... -
Design of 300 ghz combined doubler/subharmonic mixer based on schottky diodes with integrated mmic based local oscillator
In this paper the design and experimental characterization of a combined doublersubharmonic mixer based on Schottky diodes which uses a 75 GHz MMIC based local oscillator is presented. This solution integrates in the same ... -
Labyrinth metasurface for biosensing applications: numerical study on the new paradigm of metageometries
The use of metasurfaces operating in the terahertz regime as biosensor devices has attracted increased interest in recent years due to their enhanced sensitivity and more accurate detection capability. Typical designs are ... -
A millimeter-wave 4th-harmonic Schottky diode mixer with integrated local oscillator
In this paper the design and experimental validation of a fourth-harmonic mixer based on Schottky diodes working around 300 GHz is presented. The main novelty of this work consists in the integration of an MMIC-based local ... -
Moisture content estimation models of flour matrices in the 67-110 GHz frequency range using a nondestructive and contactless monitoring system
This work addresses the lack of moisture content estimation models for food products in the millimeter-wave frequency range and showcases the potential of this range for designing compact, cost-effective, and in-line food ... -
Remote sensing for plant water content monitoring: a review
Las redes sociales se han convertido en una de las principales fuentes de información, especialmente entre los más jóvenes. Al mismo tiempo, se ha incrementado la producción y circulación de información falsa o fake news ... -
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, ...
