I am currently simulating a chiral nanostructure in FDTD, mainly focussing on the farfield response, which works fine.
I now want to simulate/access the chiral nearfields, aiming to calculate the optical chirality enhancement Ĉ of my structure.
An example for this optical chirality enhancement Ĉ can be found here: Figure 3 in https://doi.org/10.1021/acsphotonics.6b00147 :
Here, the optical chirality enhancement Ĉ is calculated as:
As this is hardly a novel concept, I was hoping that Lumerical already has built in commands for extracting these complex nearfields or - even better - the optical chirality enhancement Ĉ, directly. If not, some pointers as to how to best extract these fields in order to calculate the optical chirality enhancement Ĉ would be appreciated.
Thanks!

Currently you can export E and H fields directly from the monitor, by using script like this:
E=getresult("monitor","E");
H=getresult("monitor","H");
Ex=E.Ex;
Ey=E.Ey;
Ez=E.Ez;
Hx=H.Hx.
Hy=H.Hy;
Hz=H.Hz;
Bx=Hx*mu0;
etc then do the cauculation.
Please try and let me know if you have questions.

Hi Guilin,
thanks for the answer!
While I was aware of the scripting language to extract fields, I am still not sure whether these are the scalar or the complex fields.
Maybe you can provide some further insight here.
Thanks in advance.

The frequency-domain result from a monitor is complex, and vectoral since it has 3 components.
