Approximately 160 regular technical papers and approximately 30 Special Session papers are expected to be presented at EMC 2009 in Austin. The Technical Paper Sessions are aligned according to technical topic areas associated with the IEEE EMC Society Technical Committees.The greatest number of papers received was in the topic area of EMC Measurements (TC2). Over 40 papers are expected on topics ranging from military and commercial EMC measurements as well as both emissions and immunity measurement issues. Measurement issues, such as measurement techniques and errors, are covered in these sessions as well as various measurement environments like Open Area Test Sites (OATS), shielded rooms, reverberation chambers, and anechoic rooms, and antenna techniques.The next largest topic area was EMI Control (TC4). Once again, over 40 papers are expected on topics covering the entire range of EMI design, analysis, and control. Shielding techniques, cable termination techniques, printed circuit board (PCB) design and analysis, as well as specialized areas such as power supply design and I/O filter design are just a few of the topics covered in this group of papers. Both military and commercial applications are included for emissions as well as immunity, including electrostatic discharge, lightning strike, medical, automotive, SAR, and many other subtopics.Computational Electromagnetics (TC9) is expected to include 25 papers on various modeling and simulation techniques, using fullwave methods, quasi-static methods, as well as simple circuit methods. Validation of all simulation techniques is an important subtopic within this general area. Papers in these sessions will include details on the inner workings of some of the simulation techniques, such as Method of Moments, Finite-Difference Time-Domain, Finite Element Method, Finite Integration Technique, and many others. These techniques are also applied to a wide range of applications, such as PCB analysis, antenna analysis, automotive, SAR, near field and far field effects, and many other subtopics.Signal Integrity (TC10) has become very important, especially for signals above 1 Gb/s, for which the more traditional analysis methods may not apply and more complex methods are required for accurate results and fully functioning circuits. These sessions will include about 20 papers on topics including common mode filtering, electromagnetic band gap structures (EBG), impedance matching and equalization, crosstalk, power integrity, PCB via effects, and many more subtopics.High Power Electromagnetics (TC5) is expected to have approximately ten papers on a variety of topics concerned with high power EM. Topics include wide ranging areas such as NEMP, Electromagnetic bombs, electrostatic discharge, lightning, and others for both military and commercial applications. Mobile, airborne, and fixed applications are included in this topic area.The newest technical topic area for the EMC Society is the area of Nanotechnology (TC11). Six papers are expected in this session. Topics include carbon nanotubes, composite materials, and others. Measurements, design, and analysis are discussed in the various papers.EMC Management (TC1) will have a session with topics covering EMC education, management processes, best practices, and methodologies. Various EMC related standards are included in this topic area.
