"gmie_cpp" -- A general purpose Mie scattering code in C++

General Descriptions:

Electromagnetic scattering of plane wave by a sphere (Mie scattering). The sphere can be magnetic. The surrounding medium can be absorbing and magnetic.

Prerequisites:

A C++ compiler supporting C++11. The author tested the code using the gcc version 6.2.0.

Usage:

1. Modify the compilation parameters in "Makefile" according to your environment. In particular,please change the "CXX" (= C++ complier).
2. Specify the input parameters in "gmie_call.cpp".
3. Compilation and linking are performed by    make
4. Run the executable by    ./gmie

Output:

Output results are Qsca, Qabs, Qext, and two elements of amplitude scattering matrix (S1, S2). In absorbing medium, Qsca, Qabs, and (S1, S2) are set to NaN, because these parameters are not defined.

Theory:

Theoretical basis can be found in
