At Sonnet, we've been developing 3D planar EM software since 1983, and our software has earned a solid reputation as the world's most accurate commercial high frequency planar electromagnetic (EM) analysis tool suite for single and multi-layer planar circuits and antennas. Our software provides very precise layout-based electrical model extraction of passive circuits and planar transmission lines from kHz through THz frequencies.
Founded in 1983 by Dr. James C. Rautio, Sonnet Software Inc. is a private company dedicated completely to the development of commercial high frequency EM software. We take great pride in providing quality technical support for our products--which we believe to be crucial for high-end technical software products.
Sonnet Software, Inc. is based in Syracuse, NY, USA with representatives across the globe.
