Abstract

Highlights: A new version of the Multiple Sphere T Matrix code is described. The system can now include multiple plane boundaries separating layers of different refractive index. The spheres can also form 2D periodic structures. Abstract: An extension of the parameter space available to the Multiple Sphere T Matrix (MSTM) code is described. The code can now calculate electromagnetic scattering and absorption characteristics of multiple spheres that are placed adjacent to multiple plane boundaries perpendicular to the z direction, with each boundary separating layers of different complex refractive index. The spheres can also form infinitely periodic structures in the x − y plane. The code retains all previous features, such as the spheres being comprised of optically active materials and having positions internal or external to other spheres. Example calculations are presented to demonstrate the veracity of the code.
