Review:
Discrete Dipole Approximation (dda)
overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
The Discrete Dipole Approximation (DDA) is a numerical computational method used to simulate and analyze the scattering and absorption of electromagnetic waves by particles with arbitrary shapes and compositions. It divides a target particle into an array of polarizable points (dipoles) to model complex geometries that are difficult to analyze with traditional methods, enabling detailed studies in fields such as optics, atmospheric science, and nanotechnology.
