Recent technology developments in the sonnet suites of planar electromagnetic analysis software

Sonnet is a high accuracy planar method of moments based electromagnetic analysis. Recent developments are described. These include multi-core CPU and cluster computing speed enhancement, full 64 bit addressing, enhanced lumped model extraction, modeling and measurement of dielectric anisotropy, a new empirical model of metal roughness, microvia array simplification, diagonal port de-embedding/calibration, interpolation, port tuning, and MATLAB interoperability.
