Microwave Engineering and Applied Electromagnetism

Picture : Antennas: numerical methods and systems (the Wheel-of-Time comprising 10
connected UWB antennas devoted to near-field imaging in the 1-to-5 GHz frequency range).

The group forms a multidisciplinary team, involving diverse aspects related to Microwave Engineering and Electromagnetics: microwave and millimetre-wave devices and materials, satellite and wireless propagation and sensing, antenna technology and numerical electromagnetic. It counts about 45 members, among which 6 professors and 25 Ph.D. students. It also benefits from the tools and expertises available in two UCL technological facilities: Winfab, dedicated to micro- and nano-fabrication, and Welcome, dedicated to electronic and communications measurements.

Principal Investigators :

Christophe Craeye, Isabelle Huynen, Claude Oestges, Jean-Pierre Raskin, Danielle Vanhoenacker

Research Areas :

  • On-wafer wideband characterization and fabrication of advanced Silicon-on-Insulator MOSFETs and substrates for microwaves and millimeter-waves applications
  • Design, modelling, fabrication and measurement of active and passive microwave circuits (integrated and hybrid)

  • Improved ray-tracing tool including diffuse scattering
  • Electromagnetic modelling of body area channels
  • Antennas and antenna array technology

  • Computational electromagnetics based on integral equations
