Exploring the Potential of Six-Port Technology in Microwave Nondestructive Testing: Current Status and Future Directions

Kamel Haddadi

Since its introduction in the late 1960s, six-port technology has served as a valuable tool for determining the amplitude and phase of microwave signals. This purely passive technology offers adaptability at high frequencies, extending its applicability up to the terahertz (THz) level. However, its...

Phonon polaritons impact atmosphere transparence in the TeraHertz range

Jeyan Bichon, Denis Petitprez, Hervé Herbin, Jean-Francois Lampin, Romain Peretti, Sophie Eliet

<div><p>Atmospheric aerosols impact the climate by modifying the radiative balance of the planet and the microphysical properties of clouds and by altering the biogeochemical balance of the atmosphere. Above all, some aerosols exhibit fascinating effects due to the phonon-polaritons...

Room-temperature continuous-wave Terahertz generation with an intersubband mid-infrared photomixer

Quyang Lin, Jean-Francois Lampin, Guillaume Ducournau, Hua Li, Emilien Peytavit, Stefano Barbieri

A Terahertz photomixer pumped by mid-infrared photons at 10µm wavelength is demonstrated. The device active-region consists of an AlGaAs-GaAs multi-quantum-well heterostructure embedded into a matrix of metallic patch-antenna resonators, electrically connected to the arms of a log-spiral antenna....

Nonlinear modelling of AlN/GaN HEMT accounting for self-biasing effect during RF step stress: analysis and hard-SOA

N. Said, Damien Saugnon, Kathia Harrouche, F Medjdoub, Nathalie Labat, Nathalie Malbert, Jean-Guy Tartarin

In this study, we investigate the non-linear (NL) behavior of AlN/GaN HEMT under gain compression technologies when submitted to 10 GHz single-tone RF-step stress, crucial for millimeter-wave power application robustness. We evaluate AlN/GaN transistors, targeting high-power amplifiers with...

THz scanning near-field microscopy of HgTe nanocrystals

Cristiane Santos, Emmanuel Lhuillier, Edouard Lebouvier, Benjamin Walter, Marc Faucher, Jean-Francois Lampin

Far-field terahertz imaging is limited by diffraction to resolutions in the tens of micrometers range. On the other hand, near-field optical microscopy is a technique that shows permittivity contrasts at the nanoscale. We present here images of HgTe nanocrystals grown by chemical synthesis in...

Can the THz-TDS detect trace gases?

Noureddin Osseiran, Jeyan Bichon, Sophie Eliet, Romain Peretti

The THz-TDS is a versatile technique and can be used to probe gas phase molecules. We are pushing the technique to its limit to try and detect trace gases at the sub-ppm levels. The experiments served as a reference for a quantitative approach that permits to extract the concentration of a probed...

Towards the elimination of water in THz-TDS data

Noureddin Osseiran, Jeyan Bichon, Sophie Eliet, Romain Peretti

<div><p>One of the most problematic points in THz-TDS is the absorption induced by water lines. This absorption complicates and biases the fitting algorithms. We propose here an approach to eliminate water from TDS data. The 1parameter model can eventually be used to quantify water...
