getemesweep - Script command

Gets the user s-matrix result from a propagation sweep, mode convergence sweep, or perturbative wavelength sweep.

Examples

This code will set up, run and collect the user s-matrix result from the propagation sweep tool in Analysis mode. The result from the propagation sweep is packaged in a dataset called "S".

# set propagation sweep settings
setemeanalysis("propagation sweep",1);
setemeanalysis("parameter","group span 2");
setemeanalysis("start",10e-6);
setemeanalysis("stop",200e-6);
setemeanalysis("number of points",10);

# run propagation sweep tool
emesweep;

# get propagation sweep result
S = getemesweep('S');

# plot S21 vs group span
s21 = S.s21;
group_span = S.group_span_2;
plot(group_span,abs(s21)^2);

This code will set up, run and collect the user s-matrix result from the mode convergence sweep tool in Analysis mode. The result from the mode convergence sweep is packaged in a dataset called "S_mode_convergence_sweep".

# set mode convergence sweep settings
start_mode = 4; #set smaller number of modes for convergence test
mode_interval = 1; #set mode interval for convergence test
setnamed("EME","number of modes for all cell groups",25); 
setemeanalysis("mode convergence sweep", 1);
setemeanalysis("start mode", start_mode);
setemeanalysis("mode interval", mode_interval);

# run mode convergence sweep tool
emesweep("mode convergence sweep");

# get mode convergence sweep result
S_mode = getemesweep("S_mode_convergence_sweep");

# plot S21 vs number of modes
s21 = S_mode.s21;
modes = S_mode.modes;
plot(modes, abs(s21)^2);

This code will set up, run and collect the user s-matrix result from the perturbative wavelength convergence sweep tool in Analysis mode. The result from the wavelength convergence sweep is packaged in a dataset called "S_wavelength_sweep".

# set wavelength convergence sweep settings
start_lam = 1.5e-6; #set start wavelength [m]
end_lam = = 1.6e-6; #set end wavelength [m]
lam_res = 100; #set wavelength for convergence test
setnamed("EME","number of modes for all cell groups",25); 
setemeanalysis("wavelength sweep",1);
setemeanalysis("start wavelength",start_lam); 
setemeanalysis("stop wavelength",end_lam);
setemeanalysis("number of wavelength points",lam_res);

 # run wavelength convergence sweep tool
emesweep("wavelength sweep");

 # get mode convergence sweep result
S_lambda = getemesweep("S_wavelength_sweep");

# plot S21 vs number of wavelength
s21 = S_lambda.s21;
lambda = S_lambda.wavelength;
plot(lambda, abs(s21)^2);
