AddCircWaveGuidePort

AddCircWaveGuidePort(CSX, prio, portnr, start, stop, radius, mode_name, pol_ang, exc_amp, varargin)

Full definition:

function [CSX,port] = AddCircWaveGuidePort( CSX, prio, portnr, start, stop, radius, mode_name, pol_ang, exc_amp, varargin )

Create a circular waveguide port, including an optional excitation and probes

Note:

The excitation will be located at the start position in the given direction
The voltage and current probes at the stop position in the given direction

input:

CSX: complete CSX structure (must contain a mesh)
prio: priority of primitives
start: start coordinates of waveguide port box
stop: stop coordinates of waveguide port box
radius: circular waveguide radius (in meter)
mode_name: mode name, e.g. ‘TE11’ or ‘TM21’
pol_ang: polarization angle (e.g. 0 = horizontal, pi/2 = vertical)
exc_amp: excitation amplitude (set 0 to be passive)

optional (key/values):

varargin: optional additional excitations options, see also AddExcitation
‘PortNamePrefix’: a prefix to the port name

output:

CSX: modified CSX structure
port: port structure to use with calcPort

example:

% create a TE11 circular waveguide mode, using cylindircal coordinates
start=[mesh.r(1)   mesh.a(1)   0  ];
stop =[mesh.r(end) mesh.a(end) 100];
[CSX,port] = AddCircWaveGuidePort( CSX, 99, 1, start, stop, 320e-3, 'TE11', 0, 1);
