The history and goals of the effort to establish the Suite, the key requirements from benchmarks that can support advances in simulation tools and computational methods, and the process being followed by the volunteer committee formed by the authors to produce the Suite are described. The first three benchmarks in the Suite and the steps that were taken to elevate them from potential candidates to effective benchmarks are presented.

The measurement of through adapters gives two conditions only, but neither open nor short adapter gives any useful condition. The results from lines with length L and length 2L can be used to derive the result for through adapters. This paper proposes one approach with a 2-impedance model, which has one shunt impedance and one series impedance. This model can be used with more complicated structures than the single impedance model

In this method, the general forms of the spectral-domain Green's functions for multilayer media are derived first. The spatial-domain Green's functions are then obtained by the discrete complex-image method, which obviates the time-consuming numerical evaluation of the Sommerfeld integral. The Rao-Wilton-Glisson basis functions are employed to provide necessary flexibility to model arbitrary shapes. To expedite the computation of frequency response over a broad band, a reduced-order model is presented using asymptotic waveform evaluation. Numerical results of multilayer circuits and antennas are presented to show the efficiency and accuracy of this method.

The arbitrarily shaped microstrips are discretized using triangular elements with Rao-Wilton-Glisson basis functions. These basis functions are then projected onto a rectangular grid, which enables the calculation of the resultant matrix-vector product using the fast Fourier transform. The method retains the advantages of the well-known conjugate-gradient fast-Fourier-transform method, as well as the excellent modeling capability offered by triangular elements. The resulting algorithm has the memory requirement proportional to ( ) and the operation count for the matrix-vector multiplication proportional to ( log ), where denotes the number of unknowns. The required spatial Green's functions are computed efficiently using the DCIM, which further speeds up the algorithm. Numerical results for some microstrip circuits and a microstrip antenna array are presented to demonstrate the efficiency and accuracy of this method.
