skrf.media.media.DefinedGammaZ0
- class skrf.media.media.DefinedGammaZ0(frequency=None, z0_port=None, z0=50, Z0=None, gamma=1j)[source]
A media directly defined by its propagation constant and characteristic impedance.
- Parameters:
frequency (
Frequency
object or None) – frequency band of this transmission line medium. Default is None, which produces a 1-10ghz band with 101 points.z0_port (number, array-like, or None) – z0_port is the port impedance for networks generated by the media. If z0_port is not None, the networks generated by the media are renormalized (or in other words embedded) from the characteristic impedance Z0 of the media to z0_port. Else if z0_port is None, the networks port impedances will be the raw characteristic impedance Z0 of the media. (Default is None)
gamma (number or array-like, optional) –
complex propagation constant. gamma must adhere to the following convention:
positive real(gamma) = attenuation
positive imag(gamma) = forward propagation
Default is 1j (lossless).
z0 (number or array-like, optional.) – complex characteristic impedance of the media. Default is 50 ohm.
Z0 (number, array-like, or None) – deprecated parameter, only emmit a deprecation warning.
