Regardless of the accuracy of the modeling tool, each modeling exercise requires some level of validation before simulation results can be trusted. Bruce Archambeault, Ph.D. and Samuel Connor IBM Research Triangle Park, NC The need to validate simulations and model results has never been more vital. Full-wave and quasi-static simulation tools using many different modeling … [Read more...]

Software Simulation Boosts the Efficacy of PCB Design
Adding an effective package to the design cycle can pinpoint areas critical to EMC compliance Dirk Müller, FlowCAD, Munich, GERMANY Ultimately, electromagnetic compatibility can be validated only in the measurement chamber with existing prototypes. Those tests are time consuming and expensive. There are various ideas for cutting the costs of testing with early software … [Read more...]
Laird Cuts Staffing and Closes Hungarian Plant
Laird plc., a global supplier of EMI shielding devices and antennas, is in the process of cutting its staff by around 5000 or 54 percent. The company is closing its manufacturing facility in Hungary, which has 500 employees, and will close or downsize three of its facilities in the U.S. Production from these sites will be transferred to Mexico and China. These steps will lead … [Read more...]

EMC in Space …
Successfully dealing with EMC in space systems requires strong EMC engineering Daryl Gerke, PE, and William Kimmel, PE Many of us in the EMC business came of age during the “space race” of the 1950s, 60s, and 70s. We well remember names like Sputnik, Mercury, Gemini, and of course, Apollo. Some of us in the EMC business have even been fortunate enough to spend some (or all) or … [Read more...]
