Radiative forces [N] versus frequency for h = 400 nm, T = 450 K, and ϕ = 50°: F g is the conservative, attractive gradient force, exerted by non-homogeneous fields of evanescent waves (red); F x (black) and F z (blue) are the lateral and normal repulsive, non-conservative forces, induced by the corresponding components of the Poynting vector, respectively.
