About



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.

Products to fit your workflow.

Sonnet Suites
Sonnet's suites of high-frequency electromagnetic (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.

Sonnet Lite
Sonnet Lite™ is a free feature-limited version of Sonnet's professional Sonnet Suites, which provides EM analysis to thousands of companies across the globe. Many major manufacturers of high-frequency components and boards depend on Sonnet to analyze their predominantly planar high-frequency designs from 1 MHz through several THz.
