IEMN – Council Room
The video presents the facilities, the large equipment and the researchers involved in the ExCELSiOR project.
Specifically, the video present an overview of the project and the new environmental controlled spaces of IEMN where ExCELSiOR facilities are installed. The three large ExCELSiOR ‘s instruments are then successively presented. An interview of a PhD student who his research is directly connected to the project as well as an interview of the director of the start-up ‘Vmicro’ show the training and innovation impacts of ExCELSiOR.

At nano level (nano-characterization) and at high frequencies (THz), major challenges are currently installed and measurement as well as characterization techniques have progressed during last years. This day main goal is to provide an overview of several research fields/applications currently under development : free-space characterization of materials, probing at THz frequencies, as well as very small scale measurement (microwave nano – probing and near-field THz). Applications of sub- TeraHertz/THz are also displayed through wireless communications, frequency multiplication and meteorology. This day, organized by IEMN and Rohde & Schwarz, will merge a group of lead researchers in these areas and a tour of the experimental facilities will be proposed at the end of the event.

9:15 → Free space calibration and S parameters measurement test bench for the dielectric material characterization in Ka, W and D-band by Daniel Bourreau, TELECOM Bretagne
This presentation deals with our experience on free space calibration techniques and measurements at millimeter waves without „Time Domain Gating“, in the Ka, W and D bands. Simulated and measured S-parameters for dielectric slabs show the validity of the permittivity extraction method over the frequency bands. This test bench could be also used for the metamaterial and non-solid material characterizations.
9:55 → Critical success factors for wafer-level measurements at THz frequencies
by Andrej Rumiantsev, MPI
Key requirements for precise wafer-level measurements at sub-mm wave frequency range such as stability of the probe system, positioning accuracy and contact repeatability as well as loss in the measurement path. Special attention will be given to the system S-parameter calibration and to methods for minimising calibration residual errors.

10:50 → THz technology for ground-based & space weather forecasting and meteorological applications by Gerrit Maschwitz, Radiometer Physics GmbH
This talk presents the latest advances in the development of ground based and space based millimeter and sub-millimeter wave radiometric instruments for the atmopheric remote sensing. As an example, passive ground based radiometer with unprecedented accuracy used to observe water vapor and temperature profiles will be presented. Active ground based active systems such as FMCW radar and scintillation radiometers have been recently developed in order to sound clouds and monitor evaporation processes happening close to the ground. Finally, a space based instrument (ICI) is currently under development for the next generation of polar orbiting meteorological satellite (MetOp-SG) to observe high altitude ice clouds.
11:30 → Body-scanner by Christian Evers, Rohde & Schwarz
This topic deals with the presentation of the active millimeter wave range body scanner, the R&S QPS100, today in operation in several airports in order to achieve safe and unimpeded traffic. The quality of a such screening system is influenced by several technical parameters, as for instance the aperture size of the antenna array, the used bandwidth, the number of single transmitting and receiving antennas and their smart arrangement. In addition the efficiency in reconstructing the image as well as an intelligent image processing are mandatory for a capable screening system.

13:25 → All-electronic 300 GHz analog Transmit/Receive frontends for multi-gigabit indoor wireless communication by Ingmar Kalfass, University of Stuttgart (Germany)
This contribution presents a full MMIC chip set realizing a 300 GHz transmit and receive RF frontend. The radio is dedicated to future high data indoor wireless communication serving application scenarii such as smart offices, data centers and home theaters. Transmission experiments in a single-input single-output, line of sight setup achieve up to 40 Gbit/s data rates. Measures to achieve the target data rate of 100 Gbit/s and electronic beam-steering are discussed.
14:05 → Schottky diode based THz circuits for coherent generation and detection by Alain Maestrini, Observatoire de Paris
This talk will present recent advances in Europe for enabling compact, low-noise THz coherent receivers working at room temperature using MMIC-like Schottky frequency multipliers and mixers for various applications including astronomy, remote sensing and instrumentation.
14:45 → Break
15:00 → TeraHertz near-field nanoscopy by Jean-François Lampin, IEMN
THz near-field nanoscopy is a new technic that allows THz waves imaging with subwavelength resolution. We use the scattering scanning near-field optical microscopy (s-SNOM) approach to image permittivity contrasts with <100 nm resolutions. Images of graphene layers at 2.5 THz will be shown as a typical example.
15:40 → MicroWave Nanoprober : a new class of instrument for hyper frequency nanoprobing by Sophie Eliet, IEMN
To answer their need, manufacturing and innovation of nanometric size-devices, require new processes as well as experimental methodologies. A new way results by combination of the Scanning Electron Microscopy (SEM) at low voltage, nanomanipulators and miniaturized probes dedicated for microwave. The miniaturized probes fabricated at IEMN seem a solution for accurate measurements of S-parameters and present a reduction of one order of parasitics magnitude.

European Microwave Week (http://www.eumweek.com/) is the first Europe’s Premier Microwave, RF, Wireless and Radar Event with about 1500 participants. A large exhibition is organized with more than 300 exhibitors including major industrial leaders in the field of microwave technology, equipment and systems and well-known research institutes.
French CNRS Research Laboratories Pavilion exhibits technological and measurement services of the five largest CNRS French laboratories operating in the frame of microwave to THz activities. The main targeted activities concern high frequency advanced technologies, devices, circuits and systems for space, military and public telecommunications and sciences applications. Technological services within RENATECH network involve III-V, Silicon devices and circuits, nanotechnologies, RF MEMS, microwave and millimeter components, calibration kits, while the measurements services offer up to THz on-wafer facilities, EMC large equipment. The stand promotes also the EQPX ExCELSiOR and LEAF.

Séminaire Excelsior sur le SMiM de PrimeNano le jeudi 28 Janvier à 10h, salle du conseil
La société PrimeNano (http://www.primenanoinc.com/) a développé un système de microscopie d’impédance à haute fréquence et en champ proche qui s’adapte sur différents AFM (Bruker et Asylum Research).
Ce système est composé en particulier d’une nouvelle pointe AFM qui a la particularité d’être blindée pour améliorer la mesure de très faible capacité.
Nous aurons la visite de Stuart Friedman directeur général qui présentera sa société et sa technologie.
