Computational Analysis of Scattering of Electromagnetic Waves by Particles

Computational Analysis of Scattering of Electromagnetic Waves by Particles   A computational model of Mie scattering was developed using COMSOL Multiphysics® and its RF Module. It solves for the scattering off a dielectric, magnetic or metal spherical particle with radius a. The model geometry is shown in Figure 1.     The air domain is …

Scattering of Electromagnetic Waves by Particles

Scattering of Electromagnetic Waves by Particles   Interaction between electromagnetic waves and particles produce unique scattering patterns that are wavelength and particle size dependent.   As electromagnetic waves propagate through matter they interact with particles or inhomogeneities and locally perturb the local electron distribution. This variation produces periodic charge separation within the particle causing oscillation …
