• ncomp (int) – Number of field components.

• igrid (int) – Control parameter of field grid type.

• ix (int) – Centre of set or beam No. i.

• iy (int) – Centre of set or beam No. i.

• xs (float) – Start x-coordinate of the grid.

• ys (float) – Start y-coordinate of the grid.

• xe (float) – End x-coordinate of the grid.

• ye (float) – End y-coordinate of the grid.

• nx (int) – Number of columns.

• ny (int) – Number of rows.

• freq (float) – Frequency.

• frequnit (str) – Frequency unit.

• amp (np.ndarray) – Array of complex amplitudes [theta, phi].
