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. WebbThe Quantum Theory of Optical Coherence June 1963 Physical Review Authors: Roy J. Glauber Harvard University Abstract The concept of coherence which has conventionally been used in optics is...

WebbAbstract The geometrical theory of diffraction is an extension of geometrical optics which accounts for diffraction. 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.
