farfield.angles_from_unflattened_transverse_wavevectors
farfield.angles_from_unflattened_transverse_wavevectors
Computes the propagation angles in free space for given wavevectors.
Evanescent modes whose transverse wavevector magnitude exceeds that of
the free space wavevector are given a polar angle of pi / 2.
Args:
- transverse_wavevectors: The unflattened transverse wavectors, with
shape
(..., nkx, nky, 2). - wavelength: The free-space wavelength.
Returns:
- None: Arrays containing the polar and azimuthal angles.
