It covers the basics of the
electromagnetic theory of light; aspects of the beam propagation method, such as Von Neumann analysis and boundary conditions; vectorial and three-dimensional beam propagation techniques; special topics, such as the wide-angle beam propagation method, discontinuities, the bidirectional beam propagation method, active waveguides, the time domain beam propagation method, and the finite-difference time-domain method; and beam propagation method analysis of integrated photonic devices.
