Silicon integrated subharmonic mixer on a photonic-crystal platform
(IEEE, 2021)
Artículo / Artikulua,
This paper presents a planar silicon integrated subharmonic mixer on top of a photonic-crystal platform. The local oscillator (LO) power is injected through a 2D photoniccrystal (PC) slab to a resonant cavity that effectively ...
Design of 300 ghz combined doubler/subharmonic mixer based on schottky diodes with integrated mmic based local oscillator
(MDPI, 2020)
info:eu-repo/semantics/article,
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 ...
A simplified design inline microstrip-to-waveguide transition
(MDPI, 2018)
Artículo / Artikulua,
A simplified design of an inline transition between microstrip and rectangular waveguide is presented in this paper. The transition makes use of a dielectric filled rectangular waveguide (DFRW) as an intermediate step, ...
Experimental validation of a Ku-band dual circularly polarized metasurface antenna
(IEEE, 2018)
Artículo / Artikulua,
The experimental validation of a Ku-band dual circularly polarized (CP) broadside-beam metasurface (MTS) antenna is presented. A radially modulated anisotropic single layer MTS has been synthesised employing sub-wavelength ...
Modified Soret lenses for dual band integrated detectors at submillimetre and millimetre wavelengths
(IEEE, 2020)
Artículo / Artikulua,
This paper presents a planar silicon integrated subharmonic mixer on top of a photonic-crystal platform. The local oscillator (LO) power is injected through a 2D photonic crystal (PC) slab to a resonant cavity that effectively ...
Dispersion properties of an elliptical patch with cross shaped aperture for synchronized propagation of transverse magnetic and electric surface waves
(MDPI, 2018)
Artículo / Artikulua,
This paper presents a novel pixel geometry for the implementation of metasurfaces requiring synchronized phase propagation of transverse magnetic (TM) and transverse electric (TE) modes. The pixel is composed by an elliptical ...
A water content continuous monitoring of grapevine xylem tissue using a portable low-power cost-effective FMCW radar
(IEEE, 2019)
Artículo / Artikulua,
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, ...
Comparison of fourth-harmonic and combined doubler/subharmonic mixer with integrated MMIC based local oscillator
(IEEE, 2019)
info:eu-repo/semantics/conferenceObject,
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. ...
A Chebyshev transformer-based microstri-to-groove-gap-waveguide inline transition for MMIC packaging
(IEEE, 2019)
info:eu-repo/semantics/article,
The gap waveguide technology has become an alternative to millimeter- and submillimeter-wave electronic circuit packaging thanks to the loss reduction associated with its use. In this paper, a simplified design of an inline ...
Design of a groove gap waveguide to microstrip inline transition
(IEEE, 2019)
info:eu-repo/semantics/conferenceObject,
In this paper the design of an inline transition between microstrip and groove gap waveguide operating at Wband is presented. The transition consists of two sections: a
tapered microstrip line and a Chebyshev transformer. ...
