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...]
High Gain Microwave Horn Antenna Supplies Constant High Intensity Fields for RFI/EMI Testing
The Model AT4418 from AR RF Microwave Instrumentation is a wideband, high gain, microwave horn antenna that provides a minimum gain of 7 dB over the frequency range of 1 GHz to 18 GHz over isotropic. The Model AT4418 supplies the constant high intensity fields necessary for RFI/EMI field testing within and beyond the confines of a shielded room. It can be used for emissions … [Read more...]
The IEC Advisory Committee on EMC (ACEC): Coordination of International EMC Standards
Since its formation, ACEC has developed a unique structure for EMC publications that is used to this day in the IEC and in other regional standardization organizations. While many EMC engineers are familiar with the electromagnetic compatibility (EMC) standards developed by the International Electrotechnical Commission (IEC), they are probably unaware of how the structure of … [Read more...]
