This robust software uses a chain matrix technique to calculate the overall system characteristics from the electric terminals to the front acoustic port. You can select piezoelectric material parameters from extensive piezoelectric database tables, including plate, beam, and bar mode elements in ceramic, crystalline, polymer and composite materials. You can also enter multiple acoustic matching and backing layers from acoustic database tables, as well as load medium characteristics. Thickness, velocity, attenuation, and cross-sectional area can be entered for each layer. Piezoelectric and acoustic material database tables can be updated from within PiezoCAD, or edited directly using Microsoft Access.
On the electrical port, you can specify a matching network including any combination of series or shunt resistors, inductors or capacitors, transformers, coaxial cable, and multiple identical piezoelectric layers that are electrically connected in parallel. You can enter any desired frequency range for the calculations, including calculating transducer response characteristics at higher harmonics.
