300 GHz optoelectronic transmitter combining integrated photonics and electronic multipliers for wireless communication
THz communications systems at carrier frequencies above 200 GHz are the key to enable next-generation mobile communication networks with 100 Gbit/s wireless data rates. One of the key questions is, which carrier frequency ... -
Addressing the impact of surface roughness on epsilon-near-zero silicon carbide substrates
Epsilon-near-zero (ENZ) media have been very actively investigated due to their unconventional wave phenomena and strengthened nonlinear response. However, the technological impact of ENZ media will be determined by the ... -
A Chebyshev transformer-based microstri-to-groove-gap-waveguide inline transition for MMIC packaging
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 ... -

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 gap waveguide-based compact rectangular waveguide to a packaged microstrip inline transition
In this paper two different simple to design and easy to manufacturing transitions from a microstrip to rectangular waveguide based on ridge and groove gap waveguides are studied. The first one is based on a combination ... -
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 ... -
Modified Soret lenses for dual band integrated detectors at submillimetre and millimetre wavelengths
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 ... -
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 ... -
Response of complementary split ring resonators in composite stratified substrate integrated waveguide
In this work, the behavior of a Complementary Split Ring Resonator (CSRR) operating within the quasi-static resonance regime and embedded in a composite stratified Substrate Integrated Waveguide (SIW) with two different ... -
Silicon carbide as a material-based high-impedance surface for enhanced absorption within ultra-thin metallic films
The absorption of infrared radiation within ultra-thin metallic films is technologically relevant for different thermal engineering applications and optoelectronic devices, as well as for fundamental research on sub-nanometer ... -
Silicon integrated subharmonic mixer on a photonic-crystal platform
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 ... -
A simplified design inline microstrip-to-waveguide transition
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, ... -
Spectrally stable thermal emitters enabled by material-based high-impedance surfaces
Radiative thermal engineering with subwavelength metallic bodies is a key element for heat and energy management applications, communication and sensing. Here, we numerically and experimentally demonstrate metallic thermal ... -
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 ... -
Twin lossy mode resonance on a single D-shaped optical fiber
This letter presents the fabrication of dual lossy mode resonance (LMR) refractometers based on titanium dioxide (TiO2) and tin oxide (SnO2) thin films deposited on a single side-polished D-shaped optical fiber. For the ...
