六、内容简介:Microwave/RF devices are mission-critical components for a variety of electronics systems. Using three-dimensional (3-D) electromagnetic (EM) field simulators to design such devices is considered a must for most microwave/RF engineers today. Since today’s personal computer outperforms many super computers from ten years ago, commercial EM simulators are widely available and can solve many practical problems on a low-cost desktop system. At the same time, function integration, miniaturization, and high performance requirement challenges microwave/RF component design methodology. EM-based design remains a very time-consuming process. Concept of physics-based surrogate model, space-mapping-based optimization, tuning and modeling methods are explained through more examples of common sense and engineers’ intuition. Through low-fidelity physics-based “coarse models”, space mapping techniques model, tune and/or optimize a high-fidelity “fine model.” With very little data from an “expensive” fine model, fast design optimization, fast tuning and/or fast modeling are achieved. Recent development includes response correction, frequency scaling, and feature points techniques. The techniques are demonstrated with examples in design, tuning and modeling of microwave devices and in other fields.
