About Sonnet

Sonnet software is dedicated to the development of high-frequency electromagnetic (EM) analysis software. At Sonnet, we provide a full line of Electromagnetic (EM) EDA software products optimal for high-frequency analysis.

Sonnet's suites of high-frequency EM Software are aimed at today's demanding design challenges involving predominantly planar (3D planar) circuits and antennas. Predominantly planar circuits include microstrip, stripline, coplanar waveguide, PCB (single and multiple layers) and combinations with vias, vertical metal sheets (z-directed strips), and any number of layers of metal traces embedded in stratified dielectric material.

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 planar EM analysis package for single and multi-layer planar circuits and antennas.

Sonnet Software Inc., founded by Dr. Rautio, is a private company, dedicated completely to the development of commercial EM software. We take great pride in providing quality technical support for our products--which we believe to be very important for high-end technical software products.

Sonnet is based in Syracuse, NY, USA with representatives across the globe.

As a representative of CST of America, Sonnet offers the CST STUDIO SUITE™ software for full 3D EM analysis to North American customers. Together, the Sonnet Suites and the CST STUDIO SUITE™ provide high frequency designers and research specialists unparalleled capability for accuracy, stability and ease of use for a wide range of planar and full 3D EM analysis challenges.
