classmethod Coaxial.from_Z0_Dout(frequency=None, z0=None, Z0=50, epsilon_r=1, Dout=0.005, **kw)[source]

Init from characteristic impedance and outer diameter

  • frequency (Frequency object) –
  • z0 (number, array-like, or None) – the port impedance for media. Only needed if its different from the characterisitc impedance of the transmission line. if z0 is None then will default to Z0
  • Z0 (number) – desired characteristic impedance
  • Dout (number, or array-like) – outer conductor diameter, in m
  • epsilon_r=1 (number, or array-like) – relative permittivity of the dielectric medium
  • **kw – passed to __init__
