Professor of Engineering à Saint Joseph University
  • Liban - Beyrouth
  • Je travaille ici depuis septembre 2015

I teach more than 5 different courses and many lab courses. I have more than 600 hours of teaching experience. The covered courses are: Antenna, Radar, Satellite, Embedded systems, Electromagnetism, Calculus IV, Telecom I and II, digital electronics.

Project Manager à Maxwell Innovation Lab
  • Liban - Beyrouth
  • septembre 2017 à mars 2019

Serve the innovation needs of our clients through state of the art lab facilities and knowledge

Research Engineer à XLIM laboratory
  • France
  • janvier 2014 à janvier 2015

Conception and realization of an antenna system, based on Electromagnetic Band Gap (EBG) Antenna, for monitoring and tracking of patients in hospitals

Tasks:
• Design and manufacturing of an innovative agile beam forming antenna
• Design and manufacturing of a Beam Forming Network (BFN) allowing the beam formation.

Research Engineer à XLIM Research Institute laboratory – Limoges University
  • France
  • janvier 2010 à janvier 2013

In collaboration with THALES Systèmes Aéroportés - European project
Theme: Innovative DEsign Architecture for Thin electronic steering Antenna (IDEATA)
Objectives: propose technological developments for low cost active phased array antennas. Develop efficient
models for optimization of broadband multi-layered antennas and broadband beam forming network.
Tasks:
* Design and fabrication of a thin tile consisting of an 4x4 antenna array with a 16 channels beamforming
network
* Complex antenna simulation and array synthesis/ analysis
* Development of an extrapolation / interpolation method to extend small array data to large array data
* Rigorous electromagnetic simulations to extract base material permittivity
* Modeling and Characterizing of Active devices (power amplifiers, mixer, low noise amplifier, multi-
function-chips)
* Analysis of interactions between active components and circulator electromagnetic environment

PhD à Xlim Laboratory
  • France
  • janvier 2007 à janvier 2010

Studying interaction between antennas and power amplifiers in order to quantify the distortion and predict the performance of power amplifiers in the presence of an antennas array.

Tasks:
• Optimization of an array of antennas in TX chains

• Development and experimental characterization of an electromagnetic array macro-model that accounts for the strong mutual coupling among microstrip antennas.

• Bilateral behavioral modeling of power amplifiers based on nonlinear scattering functions which allows taking into account large output loading impedance mismatches

• Building a demo to validate theoretical aspects
