calcPort

calcPort(port, SimDir, f, varargin)

Full definition:

[port] = calcPort( port, SimDir, f, varargin)

Calculate:

• voltages and currents

• the propagation constant and the characteristic impedance (if applicable)

The port has to be created by e.g. AddMSLPort(), AddLumpedPort() or AddCurvePort

input:

• port: return value of AddMSLPort()

• SimDir: directory, where the simulation files are

• f: frequency vector for DFT

variable input:

• ‘RefImpedance’: use a given reference impedance to calculate inc and ref voltages and currents default is given port or calculated line impedance

• ‘RefPlaneShift’: for transmission lines only, See also calcTLPort for more details

• ‘SwitchDirection’: 0/1, switch assumed direction of propagation

• ‘SignalType’: ‘pulse’ (default) or ‘periodic’

output:

• output signals/values in time domain (TD):

  • port.ut.tot: total voltage (time-domain)

  • port.ut.time: voltage time vector

  • port.it.tot: total current (time-domain)

  • port.it.time: current time vector

• output signals/values in frequency domain (FD):

  • port.f: the given frequency fector

  • port.uf.tot/inc/ref: total, incoming and reflected voltage

  • port.if.tot/inc/ref: total, incoming and reflected current

  • port.ZL_ref: used reference impedance

  • port.P_inc: incoming power

  • port.P_ref: reflected power

  • port.P_acc: accepted power (incoming minus reflected, may be negative for passive ports)

• if port is a transmission line port:

  • port.beta: propagation constant

  • port.ZL: characteristic line impedance

example:

port = calcPort(port, Sim_Path, f, 'RefImpedance', 50);
