Context
Future generation of ultra high frequency electromagnetic sensing and communication systems will be faced with several major requirements such as increased frequency capabilities, ultraminiaturization, sustainability, ‘greenification’ and autonomy, cost reduction and affordability. To reach these objectives, compactness, architecture simplification , immunity to electromagnetic interferences, adaptiveness to environment and multifunctionnality will play a major role. The implementation of nanotechnologies defined as the synthesis of new materials and/or process of nano-objects such as nanowires, nanotubes and nano structuration of materials appears as a major trend to satisfy More Moore, More than Moore and beyond CMOS requests.
Integration of nanotechnologies offers new perspectives, both in sensors design and electronics processing up, to definition of innovative platforms with embedded health monitoring functions and advanced wireless networks. In consequences, new fields of applications, up-to-now inaccessible, appear, taking advantage of the portability of embedded systems with high sensitivity and resolution and have to benefit to the whole scientific community (physics, sciences of the universe, biology for example). In addition, the advent of the nanotechnologies also gives a revival to the instrumentation, by allowing today to miniaturize instruments, while increasing their performances.
Research thrusts
In the area of ultrafast communications where time control becomes more and more critical, electronic components and devices market turn gradually to optically-assisted solutions in order to realize the fastest immune remote activation with a time resolution in the range of few femtoseconds. Dedicated time domain methods of design, modelling, process and characterization of new materials and confined light/matter interactions must be established. Multiscale approaches are required from macrospcopic down to submicronic scale at which elementary particles such as photons, electrons and atoms meet and communicate to each others by transfer of energy guaranteeing the multifunctionality of a new generation of 3D high frequency systems.
