Abstract	Availability of computationally efficient techniques for system performance simulation over a broad frequency range is essential in electromagnetic compatibility. Deriving samples of the desired observable from frequency-domain computations at uniform intervals may be prohibitively time consuming for highly resonant structures. This paper examines a technique for generating of wide-band data from Method-of-Moments (MoM) simulation by employing the Neville-type Stoer-Bulirsch inter-polation algorithm supported by adaptive frequency sampling of the observable. The key feature of the approach is its ability to perform interpolation over a wide frequency band with a single rational interpolant. Sample numerical examples demonstrate capability of the approach to greatly improve computational efficiency of MoM-based simulation over a broad frequency band.
