POINT | Adds a | ||
| position. Point sources whose polarization is not x, y, or z | ||
| (diagonally, circularly, or elliptically polarized) can be implemented | ||
| as two or three point sources with appropriately chosen magnitude | ||
| and phase. | ||
| Parameters: x y z Ex Ey Ez mag phase | ||

3.1.7. COMMAND Group
COMPUTE | Supply control parameters to FIDO/TEMPEST. Parameters mincycles | ||
| and maxcycles control the number of cycles of the excitation | ||
| frequency that each simulation may use; setting the lower limit | ||
| occasionally helps in avoiding spurious early convergence, and the | ||
| upper puts a bound on the amount of run time. Adjusting | ||
| maxcycles to a small number such as | ||
| run, because you can get rapid feedback on whether your geometry | ||
| is correct, and whether your PMLs are likely to cause problems. | ||
| Slightly higher values are useful in the early stages of an | ||
| optimization, where extreme accuracy in penalty function evaluation | ||
| is not needed, but run time is a serious concern. See the TEMPEST | ||
| documentation for more details. Start with a value of 0.01 or 0.001 | ||
| for reltolerance, and don’t set mincycles or timestep until you really | ||
| need to. | ||
| Parameters: reltolerance maxcycles mincycles timestep | ||

3.1.8. OUTPUT Group
INDEXN | Tells tempest to produce a field file containing the real part of the | ||
| refractive index at each point. This is useful to show which | ||
| material is where in the simulation domain. | ||
| Parameters: xlo xhi ylo yhi zlo zhi file | ||
|

|
|
DECIMATE | Specify that only 1 out of decimation points is to be kept in each axis. | ||
| Parameters: xdecimation ydecimation zdecimation | ||
| Not implemented in this release. | ||
