CPW is a class allowing the calculation of Coplanar Waveguide characteristic values following geometric parameters, conductivity, relative permitivity and, loss tangent.

All method are well documented into the class.

Example:

import CPW line = CPW.CPW() //You can change your cpw parameters thanks to set method line.set_thickness(0.5e-6) line.set_width_central_line(10e-6) //You can easily calculate physical parameters line.get_inductance_per_unit_length(2e9) >>>>4.26e-7 line.get_velocity(2e9) >>>>0.399 //You can optimized your chracteristic impedance a.find_optimal_gap_separation(50., 10e9) >>>>(49.9999, 5.38152e-6)

This class is based on an article of Wolfgang Hainrich "Quasi-TEM Description of MMIC coplanar Lines Including onductor-Loss Effects" IEEE Transactions on Microwave Theory And Techniques, vol 41, n° 1, January 1993
