It introduces diffracted rays in addition to the usual rays of geometrical optics. These rays are produced by incident rays which hit edges, corners, or vertices of boundary surfaces, or which graze such surfaces.

Webb5 mars 2024 · All we can detect are outgoing waves far outside the region of scattering. For an ingoing plane wave ei→k ⋅ →r, the wavefunction far away from the scattering region must have the form ψ→k(→r) = ei→k ⋅ →r + f(θ, φ)ei k r r. where θ, φ are measured with respect to the ingoing direction. Note that the scattering amplitude f(θ ... WebbThe theory of optical forces on spherical scatterers is here generalized to arbitrary incident fields. The interaction between spherical harmonics of different order, and the degree and azimuthal parity, is studied in detail. The resulting force from all the contributing components is presented in analytical form.
