I am currently simulating a chiral nanostructure in FDTD, mainly focussing on the farfield response, which works fine. <\/p>\n

I now want to simulate\/access the chiral nearfields, aiming to calculate the optical chirality enhancement C\u0302 of my structure.<\/p>\n

An example for this optical chirality enhancement C\u0302 can be found here: Figure 3 in https:\/\/doi.org\/10.1021\/acsphotonics.6b00147<\/a> :<\/p>\n

<\/p>\n

Here, the optical chirality enhancement C\u0302 is calculated as:<\/p>\n

<\/p>\n

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 C\u0302, directly. If not, some pointers as to how to best extract these fields in order to calculate the optical chirality enhancement C\u0302 would be appreciated.<\/p>\n

Thanks!<\/p>\n
