Treats every point in the starting field as a point source; the final field is the sum of contributions from all these sources. 2. Common Numerical Methods
Decomposes an initial optical field into plane waves, propagates each separately by applying a complex phase shift, and recombines them using an inverse Fourier transform . Numerical Simulation of Optical Wave Propagatio...
Numerical simulation of optical wave propagation involves solving Maxwell's equations or their approximations to predict how light behaves in various media. While analytical solutions are often limited to simple, idealized cases, numerical methods allow researchers to model complex real-world structures like fiber optics, waveguides, and photonic crystals. 1. Fundamental Approaches Treats every point in the starting field as
There are two primary conceptual frameworks for simulating wave propagation: the complexity of the geometry
Choosing a method depends on the required accuracy, the complexity of the geometry, and available computational power.
