fdtdx.PhasorDetector

Bases: Detector

Detector for measuring frequency components of electromagnetic fields using an efficient Phasor Implementation.

This detector computes complex phasor representations of the field components at specified frequencies, enabling frequency-domain analysis of the electromagnetic fields. The amplitude and phase of the original phase can be reconstructed using jnp.abs(phasor) and jnp.angle(phasor). The reconstruction itself can then be achieved using amplitude * jnp.cos(2 * jnp.pi * freq * t + phase).
