The microwave point of view on software validation

Validation generally consists of a "Good Agreement Between Measured And Calculated" (GABMAC) plot. Unfortunately, when one looks at microwaves-related papers, error bars are rarely plotted on measured data, and quantitative estimates of error are typically absent. Further, convergence analyses, if performed, are rarely mentioned, and test structures are not checked for sensitivity to analysis error. Meanwhile, the discussion of these issues in the antenna field is on-going and active. In fact, it has progressed to the point that you are asking for input from other technical areas. The author describes the situation in the microwave field as he sees it.
