can I ask how I can calculate normalized intensity in lumerical FDTD? in a metalens design? for example the attached photo
Hello @HalimBishoy ,
The electric field E in the frequency domain can be recorded with a frequency domain field and power monitor:
The normalized intensity can be found by taking the magnitude squared of the electric field (which can be returned from a monitor with the "getelectric" script command: https://support.lumerical.com/hc/en-us/articles/360034409974-getelectric-Script-command) and then normalizing by dividing by the maximum value. If you are new to using our scripting language, I would recommend that you take the online scripting course:
