R&D Roundup: For #handset #antenna design, space mapping trumps #EM optimization:

When it comes to handset antenna design, using full-wave electromagnetic (EM) simulators can be difficult because of high-performance requirements and space limitations. Such simulations may have to include some of the handset’s other components, which can lead to very lengthy EM simulations that are prohibitive in terms of optimization. Space mapping, which establishes mapping between a fine model of the considered device and a suitable coarse/surrogate model, can ease this process. A handset-antenna modeling and design technique that relies on space mapping has been presented by Sheng Tu, Yifan Zhang, Natalia K. Nikolova, Qingsha S. Cheng, and John W. Bandler from Ontario’s McMaster University. With space mapping, the fine model is generally accurate but intensive in terms of the central-processing-unit (CPU) burden. The coarse model, in contrast, is much faster but less...
