fields.fields_on_coordinates

fields.fields_on_coordinates​

Computes the fields at specified coordinates.

The calculation is for a batch of fields, with the batch axis being the final axis. There can also be leading batch axes. Accordingly, fields 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:​

  • electric_field: (ex, ey, ez) electric field Fourier amplitudes.
  • magnetic_field: (hx, hy, hz) magnetic field Fourier amplitudes.
  • layer_solve_result: The results of the layer eigensolve.
  • x: The x-coordinates where the fields are sought.
  • y: The y-coordinates where the fields are sought, with shape matching that of x.

Returns:​

  • None: The electric field (ex, ey, ez), magnetic field (hx, hy, hz), and the grid coordinates (x, y). The field arrays each have shape batch_shape + coordinates_shape + (num_amplitudes).
