DESCRIPTION:Antennas\, Arrays & Calibration: Beam Forming and Beam Steering
 \n\nSpeaker: Prof. Dr. Levent Sevgi - IEEE APS Distinguished Lecturer – 
 IEEE Fellow\n\nThe antenna is an electromagnetic (EM) radiator that emits 
 radio frequency power. In other words\, it is a transducer that converts v
 oltage [V] to the electric field [V/m] (or vice versa). This IEEE AP-S DL 
 talk will focus on electromagnetic radiators\, antennas\, antenna arrays a
 nd calibration. First\, antenna as a transducer will be discussed and its 
 circuit and electromagnetic models will be reviewed. Fundamental antenna t
 erms and concepts will be summarized. Then\, differences between communica
 tion and EMC antennas will be given. Finally\, antenna calibration will be
  explained. In the second part\, formation of antenna arrays will be prese
 nted and their beam forming and beam steering capabilities will be shown v
 ia a simple\, MATLAB-based ARRAY virtual tool. Any 2D array (i.e.\, linear
 \, planar\, circular\, etc.) may be designed by the user and its 2D and 3D
  radiation characteristics can be investigated using this tool. Beam formi
 ng capabilities for different locations\, number of radiators\, as well as
  for operating frequencies can be visualized. The package may be used as a
 n educational tool in many undergraduate antenna lectures. It may also be 
 used to validate and verify the finite-difference time-domain (FDTD) and m
 ethod of moments (MoM) packages in public domain or\, for example\, the on
 es supplied in [3]. Moreover\, the user may improve package and add novel 
 features by using the supplied source codes.\n\nSpeaker(s): Prof. Dr. Leve
