Abstract
We present a computer code for calculating near- and far-field electromagnetic properties of multilayered spheres. STRATIFY is one-of-a-kind open-source package which allows for the efficient calculation of electromagnetic near-field, energy density, total electromagnetic energy, radiative and non-radiative decay rates of a dipole emitter located in any (non-absorbing) shell (including a host medium), and fundamental cross-sections of a multilayered sphere, all within a single program. The developed software is typically more than 50 times faster than freely available packages based on boundary-element-method. Because of its speed and broad applicability, our package is a valuable tool for analysis of numerous light scattering problems, including, but not limited to fluorescence enhancement, upconversion, downconversion, second harmonic generation, surface enhanced Raman spectroscopy.…
