Sonnet Suite Pro 9.5.2 (1 cd)
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.
