fdtdx.compute_poynting_flux

fdtdx.compute_poynting_flux#

fdtdx.compute_poynting_flux(E, H, axis=0)[source]#

Calculates the Poynting vector (energy flux) from E and H fields.

Parameters:

  • E (jax.Array) – Electric field array with shape (3, nx, ny, nz)

  • H (jax.Array) – Magnetic field array with shape (3, nx, ny, nz)

  • axis (int, optional) – Axis for computing the poynting flux. Defaults to 0.

Returns:

Poynting vector array with shape (3, nx, ny, nz) representing energy flux in each direction

Return type:

jax.Array
