Metamaterials : design of an integrated high-impedance surface at 60 GHz, transposition and potentialities at 60 THz

Invisibility cloaking, sub-wavelength, thin antenna substrates, absorbers, etc., metamaterial structures have open many perspectives, some of them seeming futuristic while other being very practical given the current ste of the art in the domains of materials, microtechnologies and integrated optics.
this post-doctoral work will focus on the study of high-impedance surfaces and the possibility of transposition of these designs between very different frequency bands (6 GHz, 60 GHz, 60 THz) corresponding to a wide range of technologies and applications.
After a thorough bibliographic study of the current state of the art, the developments will include the design of high-impedance surfaces at the three frequency bands cited above and an experimental demonstration at 6 GHz and possibly at 60 GHz.

Design of a control system of a plane based on distributed electric propulsion

The objective of this post doctorate is to design a control system to manage the electrical power on an electric plane proposed by many electrical turbines. The aim of the work is to demonstrate the possibility to increase the propulsion efficiency by using many cooperative electrical turbines placed judiciously on plane compare to a plane having only two or four turbine. Furthermore, one idea is to completely drive the plane by adjusting in real time the power of each electrical turbine taking advantage of their high reactivity compare to classical thermal turbines. The background required for that post doctorate is a good knowledge in control system and power electronic.
