Wcalc is a tool for the analysis and synthesis of transmission line structures and related components. Wcalc provides the ability to analyze the electrical parameters of a particular structure based on the physical dimensions and material parameters. The synthesis portion calculates the required physical parameters to meet desired electrical specifications. Wcalc includes several models and places an emphasis on accuracy. Several frontends provide the user with several options for its use. Models include: - single layer solenoid inductor - single microstrip and stripline - coupled microstrip and stripline - coplanar waveguide - metal-insulator-semiconductor microstrip - coaxial cable - self and mutual inductance of two parallel rectangular bars - self and mutual inductance of two parallel circular rods Frontends include: - gtk gui - web (cgi) - scilab - octave - matlab - stdio See the file INSTALL for building and installation instructions.
