Lessons from applying IEEE standard 1597 for validation of computational electromagnetics computer modeling and simulations

In this paper guidelines and benchmark examples from IEEE standard and recommended practice 1597 for validation of computational electromagnetics computer modeling and simulations are applied with the aim of evaluating their practicality and consistency. Benchmark examples include a thin dipole antenna, a loop antenna, and a rectangular cavity with two apertures. In addition, a fourth example-consisting of a box-shaped monopole antenna on a finite plate-is measured and simulated. All examples are investigated by means of three different numerical techniques commonly applied by EMC engineers using two commercially available software tools and one self-developed software tool. Numerical results for input impedance, electromagnetic field values, farfield pattern, power budget, and shielding effectiveness obtained by the different techniques are compared and discussed with regard to the validation procedure outlined in IEEE standard 1597. Applicable simulation results are compared to results from closed-form equations and measurements. Observations with regard to differences between the techniques are outlined, and recommendations for a pragmatic application of IEEE standard 1597 are given.
