The RCWA Field Monitor collects the field profile in the frequency domain on a rectilinear grid from simulation results across some spatial region within an RCWA solver simulation.
Geometry tab
MONITOR TYPE: The monitor type and orientation. The RCWA field monitor can be 3D, 2D, 1D (linear), or 0D (a point). This option will control which of the spatial settings below are available.
X GRID SPACING: Method used to define the grid. The grid spacing can be UNIFORM or CUSTOM.
If the X GRID SPACING is set to UNIFORM, the grid point locations along the X axis are uniformly spaced in the monitor according to the following settings:
- X NUMBER POINTS: Number of grid points along the X axis.
- X: The center position of the monitor along the X axis.
- X SPAN: X span of the monitor.
- X MIN, X MAX: X min, X max position of the monitor.
If the X GRID SPACING is set to CUSTOM, the user specifies each of the grid point locations along the X axis individually. To change the grid locations, click the EDIT button to open up the MATRIX EDITOR.
If the monitor geometry is not extended in the X direction (if MONITOR TYPE is set to 2D X-NORMAL, LINEAR Y, LINEAR Z, or POINT) then only X will be available. In this case, X determines the location of the monitor along the X axis.
The grid spacing along the Y and Z directions is defined similarly.
If the RCWA Field Monitor extends beyond the RCWA simulation, any grid points outside the simulation region are ignored.
Data to record
OUTPUT EX, EY, EZ, HX, HY, HZ: Selects the electric (E) and magnetic (H) fields to record.
RETURN THETA AND PHI SEPERATELY IF NOT TABULATED: Return the incident angles theta and phi as separate parameters in the results. This is only applicable if the incident angles in the RCWA solver object are not set using the “Table” option. In new projects, this option is turned on by default. When reading an existing simulation file, this option is turned off by default.
CLIP MONITOR TO SOLVER REGION: If the monitor is larger than the solver region, clip results such that only those inside the solver region is displayed.
Results returned
- Es: Frequency domain electric field vector for the S polarized source. Returned as a function of position, wavelength/frequency, and incident angle (theta/phi).
- Ep: Frequency domain electric field vector for the P polarized source. Returned as a function of position, wavelength/frequency, and incident angle (theta/phi).
- Hs: Frequency domain magnetic field vector for the S polarized source. Returned as a function of position, wavelength/frequency, and incident angle (theta/phi).
- Hp: Frequency domain magnetic field vector for the P polarized source. Returned as a function of position, wavelength/frequency, and incident angle (theta/phi).
- Index/index preview: Refractive index as a function of position and wavelength/frequency. This result is shown as “index preview” prior to simulation, and “index” after the simulation.
- grid: Domain ID as a function of position.
