 of antenna arrays is a very long standing field in electromagnetism becaus
 e of its many applications (e.g. radar\, radio astronomy\, sonar\, communi
 cations\, direction-finding\, seismology\, medical diagnosis and treatment
 ). A host of methods have been proposed since the 40's to solve increasing
 ly difficult synthesis problems. These techniques range from analytical me
 thods (fast but limited to very specific problems) to global optimization 
 approaches (comprehensive but limited in performances due to their computa
 tional burden). Convex optimization has been shown to be a good trade-off 
 in efficiency/generality between analytical and global optimization techni
 ques. The purpose of the talk is to show that a variety of difficult anten
 na array synthesis problems can be relaxed as convex optimization problems
  and therefore efficiently solved. The synthesis of shape beams and reconf
 igurable arrays by phase-only control will be addressed.
