class TMatrix_Axisymmetric_Scatterer
The class TMatrix_Axisymmetric_Scatterer implements
a theory for scattering by an axisymmetric homogeneous
particle as described by Barber and Hill. The shape of the particle
is described by the class Axisymmetric_Shape.
Parameters:
| Parameter |
Data Type |
Description |
Default |
| lambda |
double |
Wavelength of the light
[µm].
(Inherited from Free_Space_Scatterer.) |
0.532 |
| medium |
dielectric_function |
The
optical constants of the medium surrounding the sphere,
expressed as a complex number (n,k) or, optionally, as
a function of wavelength.
(Inherited from Free_Space_Scatterer.) |
(1,0) |
| Shape |
Axisymmetric_Shape_Ptr |
The shape and size of the particle. |
Ellipsoid_Axisymmetric_Shape |
| particle |
dielectric_function |
The
optical constants of the particle, expressed as a
complex number (n,k) or, optionally, as a function of
wavelength. |
(1.59,0) |
| lmax |
int |
The
maximum polar order considered in the calculation. A
value of zero implies that the calculation should use
the value suggested by Bohren and Huffman for a
sphere.
Note: Validity of the results requires convergence over
this parameter. |
0 |
| mmax |
int |
The
maximum azimuthal order considered in the calculation.
A value of zero implies that this order should be the
same as that used for the polar order.
Note: Validity of the results requires convergence over
this parameter. |
