Output example: Field distribution inside layered Si\Ag\Si sphere and Poynting vector distribution in Ag sphere with powerflow lines calculated with Scattnlay (scripts field-SiAgSi-flow.py and field-Ag-flow.py from example section as revision ).

Limited web version is available at https://physics.ifmo.ru/mie/
To compile the source you will need a C++11 capable compiler. To use MultiPrecision feature you need to install Boost.Multiprecision library:
To compile the Python extension you need NumPy:
And to compile the Debian package you need some tools:
Compilation options
There are also an experimental CMake project and it is possible to compile into JavaScript module (using Emscripten compiler).
Python module
To build and install Python module run from the source code directory:
pip install . --user
Binary files for Ubuntu and derivative distributions can be found at Launchpad To install it you must configure the repository:
sudo add-apt-repository ppa:ovidio/scattering
sudo apt update
and then you simply install the package:
sudo apt install python-scattnlay
You can also install it from PyPi via
sudo pip install python-scattnlay
You can also git clone
and pip install -e .
to develop python package.

Scattnlay "Hello world!" example:
try {
nmie::MultiLayerMieApplied<double> multi_layer_mie;
multi_layer_mie.AddTargetLayer(core_width, index_Si);
multi_layer_mie.AddTargetLayer(inner_width, index_Ag);
multi_layer_mie.AddTargetLayer(outer_width, index_Si);
multi_layer_mie.SetWavelength(WL);
multi_layer_mie.RunMieCalculation();
double Qabs = multi_layer_mie.GetQabs();
printf("Qabs = %g\n", Qabs);
} catch( const std::invalid_argument& ia ) {
// Will catch if multi_layer_mie fails or other errors.
std::cerr << "Invalid argument: " << ia.what() << std::endl;
return -1;
}
The complete example-minimal.cc
and a bit more complicated
example-get-Mie.cc
can be found in example directory along with
go-cc-examples.sh
script with build commands.
example-get-Mie.cc
can be compiled using double precision or
multiple precision (just include -DMULTI_PRECISION=200
to use 200
digits for calculations).
