Particles

A particle is defined by its surface shape and the complex refractive index of its medium. In the case of a multilayered particle, each layer’s refractive index and surface shape should be defined.

Homogeneous particles

A homogeneous particle can be defined as an instance of the HomogeneousParticle. There are also several predefined classes for the most often used partiles.

HomogeneousParticle
Sphere
ProlateSpheroid
OblateSpheroid
ChebParticle

Layered particles

A layered particle can be defined as an instance of the LayeredParticle. There are also several predefined classes for the most often used multilayered partiles.

LayeredParticle
Layered_EqShape_Particle
Layered_EqShapeEqVol_Particle
LayeredConfocalSpheroid

Effective Medium Theory

Inhomogeneous scatterers can also be treated with the effective medium theory (EMT). An EMT particle is an instance of a class derrivered from the EMT_Particle. There are several classes implementing EMT with the most widely used EMT rules.

EMT_Particle
EMT_MGarn_Particle
EMT_IMGarn_Particle
EMT_Brugg_Particle
