Beam propagation method
text:
The beam propagation method (BPM) is an approximation technique for simulating the propagation of light in slowly varying optical waveguides. It is essentially the same as the so-called parabolic equation (PE) method in underwater acoustics. Both BPM and the PE were first introduced in the 1970s. When a wave propagates along a waveguide for a large distance, rigorous numerical simulation is difficult. The BPM relies on approximate differential equations which are also called the one-way models.
