calcWGPort

calcWGPort(port, SimDir, f, varargin)

Full definition:

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

Calculate voltages and currents, the propagation constant beta and the characteristic impedance ZL of the given waveguide port.

The port has to be created by e.g. AddWaveGuidePort().

input:

• port: return value of e.g. AddWaveGuidePort()

• 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’: use a given reference plane shift from port beginning for a desired phase correction default is the measurement plane at the end of the port the plane shift has to be given in drawing units!

• ‘RefractiveIndex’: set a material refractive index

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

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.beta: propagation constant

  • port.ZL: characteristic line impedance

  • port.ZL_ref: used reference impedance

example:

port{1} = calcWGPort( port{1}, Sim_Path, f, 'RefImpedance', 50);
