Sonnet 19.52.2025 Release Notes (release date June 2025)






Sonnet's suitesof 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.

Modeling Anisotropic Substrates

Did you know that permittivity is dependent on the direction of fields? This is called anisotropy, and not only does Sonnet support this in analysis, but we have developed a technique to characterize material as well. If you need accurate simulation, this tutorial is for you.
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. Sonnet maintains a single, dedicated focus on providing the industry's most accurate and reliable high frequency planar EM software.
