We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

Hi Debasish, thank you for posting your question. The fields recorded by frequency domain monitors are normalized to the source spectrum (see this page), but not to the source amplitude. For sources like plane wave or beams, the default source amplitude is set to 1 V/m (defining the amplitude of the electric field), and can be changed in the source settings. If you change it, you will see this affecting the field amplitude recorded by the monitors.
