Summary
Six years after the first edition was prepared, it was clear that a revised edition was in order. Continued advances in computational electromagnetics, new capabilities in commercial codes, the continual increase in computational resources, challenging new problems and a new generation of research students and engineers required new material.
Since the first edition appeared, several trends can be noted in the field. Firstly, in terms of commercial companies, there has been a significant shake-out in the market. Whilst not pretending to offer encyclopedic coverage of the large number of commercial codes available, the three codes whose application is discussed in this book, viz. CST, FEKO and HFSS, have further established themselves as amongst the market leaders in their regions of application during this period. These codes have evolved continuously, and this evolution is reflected in places in this revised edition. Secondly, whilst no fundamentally new techniques have been introduced (either in the field in general or in commercial codes in particular), a large number of additional features, improvements and enhancements have continued to extend the utility of these packages. Thirdly, after more than two decades of continual increase in CPU clock speeds in personal computers (which now dominate computational engineering), the last few years have seen clock speeds not only stagnate, but in some cases actually decrease. However, Moore's law has continued to hold sway, but in terms of multi-core and multi-processor systems. Exploiting parallelism has become essential to benefit from new hardware.
