We describe the current status of our research on reflectarray antennas operating at terahertz frequencies. We present preliminary measurements of a fixed beam reflectarray operating at 1 THz fabricated on silicon and characterized with a THz time domain system. Secondly, we study theoretically the applicability of novel reconfigurable materials, namely(More)
This paper presents the optimization design of 3D integrated inductors exploiting through silicon vias (TSV) technology to improve the quality (Q) factor in the 2-20 GHz range. The embedded inductor allows the heterogeneous integration with CMOS and MEMS components in a size-compact and low-cost manufacturing process. Results limited to our manufacturing(More)
Graphene quantum capacitors (GQC) are demonstrated to be enablers of radio-frequency (RF) functions through voltage-tuning of their capacitance. We show that GQC complements MEMS and MOSFETs in terms of performance for high frequency analog applications and tunability. We propose a CMOS compatible fabrication process and report the first experimental(More)
The modulated scattering technique is based on the use of reconfigurable electromagnetic scatterers, structures able to scatter and modulate an impinging electromagnetic field in function of a control signal. The modulated scattering technique is used in a wide range of frequencies up to millimeter waves for various applications, such as field mapping of(More)
The vast majority of disruptive innovations in science and technology has been originated from the discovery of a new material or the way its properties have been exploited to create novel devices and systems. New advanced nanomaterials will have a lasting impact over the next decades, providing breakthroughs in all scientific domains addressing the main(More)
