fields.fields_from_wave_amplitudes​

Computes the electric and magnetic fields inside a layer.

The calculation is for a batch of amplitudes, with the batch axis being the final axis. There can also be leading batch axes. Accordingly, amplitudes should have shape (..., 2 * num_terms, num_amplitudes). The trailing batch dimension is preferred because it allows matrix-matrix multiplication instead of batched matrix-vector multiplication.

Args:​

  • forward_amplitude: The amplitude of the forward-propagating waves.
  • backward_amplitude: The amplitude of the backward-propagating waves, at the same location in space as the forward_amplitude.
  • layer_solve_result: The results of the layer eigensolve.

Returns:​

  • None: The electric and magnetic fields, ((ex, ey, ez), (hx, hy, hz)).
