AIM AND SCOPE
The practical premise of the ACE workshops is the recognized fact that the trend
towards miniaturization, the increase of operating frequencies, and the emergence
of new materials make conventional CAD tools less and less adequate. If progress
is to be made, computational electromagnetism has to develop new ideas and
integrate contributions from different scientific communities. ACE workshops
were born as an open forum for such an endeavor.
We aim at addressing open issues in computational electromagnetism in a
broad perspective, gathering a reasonable number of speakers who shall present
their views and discuss them at ease with a knowledgeable and reactive audience.
In ACE’09, in particular, we focus mostly on complex responses of material
media (covering both experimental analysis and mathematical modeling), basic
formulations and discrete calculus, identification and inverse problems.
TIME SCHEDULE
ACE’09 is comprised of five sessions, each about four hours long (breaks included). The first session starts on Monday, January 12, at 9:00 am; the last one
closes on Wednesday, January 14, at 1:00 pm. The time allotted to each contributed (invited ) talk is 20 (30) minutes plus 10 (15) minutes for discussion.
