Abstract
An extension of the computational framework known as the photonic Layer Multiple Scattering (LMS) method for the simulation of electromagnetic wave scattering from dynamically varying structures is presented. The structures are made up of layers of scatterers and/or homogeneous slabs. The method is flexible since it allows for the determination of the scattering characteristics of a composite system from those of its constituent elements and appropriate propagator functions. Here, it is shown how LMS can be applied to dynamic photonic structures of spherical scatterers that change periodically throughout time. Nonreciprocal effects, without the need of magnetic materials, are demonstrated for arrays of high-index dielectric particles with time-varying permittivity.
