AddCoaxialPort

AddCoaxialPort(CSX, prio, portnr, pec_name, materialname, start, stop, dir, r_i, r_o, r_os, varargin)

Full definition:

function [CSX,port] = AddCoaxialPort( CSX, prio, portnr, pec_name, materialname, start, stop, dir, r_i, r_o, r_os, varargin )

CSX: CSX-object created by InitCSX()
prio: priority for excitation and probe boxes
portnr: (integer) number of the port
pec_name: metal property for coaxial inner/outer conductor (created by AddMetal())
materialname: substrate property for coaxial line (created by AddMaterial()) Note: this may be empty for an “air filled” coaxial line
start: 3D start rowvector for coaxial cable axis
stop: 3D end rowvector for coaxial cable axis
dir: direction of wave propagation (choices: 0, 1, 2 or ‘x’,’y’,’z’)
r_i: inner coaxial radius (in drawing unit)
r_o: outer coaxial radius (in drawing unit)
r_os: outer shell coaxial radius (in drawing unit)

variable input:

varargin: optional additional excitations options, see also AddExcitation
‘ExciteAmp’ excitation amplitude of transversal electric field profile, set to 0 (default) for a passive port
‘FeedShift’ shift to port from start by a given distance in drawing units. Default is 0. Only active if ‘ExciteAmp’ is set!
‘Feed_R’ Specify a lumped port resistance. Default is no lumped port resistance –> port has to end in an ABC.
‘MeasPlaneShift’ Shift the measurement plane from start t a given distance in drawing units. Default is the middle of start/stop.
‘PortNamePrefix’ a prefix to the port name

the mesh must be already initialized
