MEMS-Reconfigurable Metamaterials and Antenna Applications

Julien Perruisseau-Carrier, Tomislav Debogovic

This paper reviews some of our contributions to reconfigurable metamaterials, where dynamic control is enabled by microelectromechanical systems (MEMS) technology. First, we show reconfigurable composite right-/left-handed transmission lines (CRLH-TLs) hav ...

Brillouin distributed fibre sensing using phase modulated probe

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Xin Lu

A novel configuration for a Brillouin distributed sensor using a phase modulated probe is presented. It offers the combined advantages of a direct implementation using simple devices and a large immunity to noise, shifting the information from the baseband ...

A printed transition for matching improvement of SIW horn antennas

Juan Ramon Mosig, Jean-François Zürcher, Marc Esquius Morote, Benjamin Fuchs

The substrate integrated waveguide (SIW) technology allows to construct several types of commonly used antennas in a planar way. However, frequency limitations associated to commercial substrates appear in the implementation of certain types of antennas, e ...

Novel thin and compact H-plane SIW horn antenna

Juan Ramon Mosig, Jean-François Zürcher, Marc Esquius Morote

The substrate integrated waveguide (SIW) technology allows to construct several types of commonly used antennas in a planar way. However, some practical constraints limit their performances when frequencies below 20 GHz are considered. In the case of SIW h ...

Investigation of the unusual polarimetric signatures of a mountainous convective event

Alexis Berne, Jacopo Grazioli

A case study of an intense convective event occurring in the Swiss Alps (Davos) is presented. Polarimetric X-band observations of this event showed an unusual strong signature in terms of differential reflectivity Zdr, differential phase shift on backscatt ...

Sensitivity analysis of polarimetric attenuation correction algorithms

Alexis Berne, Samuel Jolivet

Polarimetry improves radar rainfall estimation. It allows a better separation of meteorological and nonmeteorological echoes, a better identification of the type of hydrometeors, and an improved correction of the attenuation due to rain affecting the signa ...

Polarimetric X-band weather radar measurements in the tropics: radome and rain attenuation correction

Marc Schneebeli Zeugin

A polarimetric X-band radar has been deployed during one month (April 2011) for a field campaign in Fortaleza, Brazil, together with three additional laser disdrometers. The disdrometers are capable of measuring the raindrop size distributions (DSDs), henc ...
