Beam Propagation Method (bpm)
overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
The Beam Propagation Method (BPM) is a numerical computational technique used to model the propagation of optical waves through various media, particularly in integrated optics, fiber optics, and photonic devices. It simplifies the analysis of complex light propagation phenomena by approximating the evolution of the electromagnetic field as it travels along a prescribed direction, enabling engineers and researchers to design and optimize optical components with higher precision.
