Localized source above a time-modulated dielectric half-space: Green's function theory Open
In this paper, we explore the two-dimensional Green's function problem above an instantaneous time-modulated dielectric half-space. In particular, we focus on studying the excitation dynamic with modulation that is carried out near the cri…

Rest-frame analysis of rotating metamaterials, gyroscopes, and century-old problems in number theory [Invited] Open
We discuss the electrodynamics of slowly rotating metamaterials as observed in their rest frame of reference, using first order polarizability theory. A formulation governing the response of an arbitrary array of scatterers to excitation u…

Rest Frame Interference in Rotating Structures and Metamaterials Open
Using the formulation of electrodynamics in rotating media, we put into explicit quantitative form the effect of rotation on interference and diffraction patterns as observed in the rotating medium's rest frame. As a paradigm experiment we…

Breach of symmetries in rotating arrays and metamaterials observed in their rest frame Open
Polarizability theory and discrete dipole approximation in a rotating medium rest-frame is developed and discussed. The analysis is based on a rigorous rotating medium Green's function, and is used to study the effect of rotation on variou…

Asymmetric micro-Doppler frequency comb generation via magnetoelectric coupling Open
Electromagnetic scattering from moving bodies, being inherently\ntime-dependent phenomenon, gives rise to a generation of new frequencies, which\ncould characterize the motion. While a standard linear path leads to a constant\nDoppler shif…

Clustering in particle chains - summation techniques for the periodic Green's function Open
1D lattice summations of the 3D Green's function are needed in many applications such as photonic crystals, antenna arrays, and so on. Such summations are usually divided into two cases, depending on the location of the observer: Out of th…

Dark mode–Faraday rotation synergy for enhanced magneto-optics Open
We examine the efficacy of Dark-mode plasmonics as a platform for enhanced\nmagneto-optics. Dark-mode of a small particle consists of two co-existing\nequal-intensity and mutually opposing dipolar excitations. Each of these two\nopposing d…

Modal and excitation asymmetries in magnetodielectric particle chains Open
We study the properties of dipolar wave propagation in linear chains of\nisotropic particles with independent electric and magnetic response, embedded\nin vacuum. It is shown that the chain can support simultaneously right-handed\nmodes (R…

Semigroups: 2.8.0 Open
The Semigroups package is a GAP package containing methods for semigroups, monoids, and inverse semigroups, principally of transformations, partial permutations, bipartitions, subsemigroups of regular Rees 0-matrix semigroups, free inverse…

Planar one-way guiding in periodic particle arrays with asymmetric unit cell and general group-symmetry considerations Open
We develop a general theory for one-way optical guiding in magnetized\nperiodic particle arrays. Necessary conditions for a non-even dispersion curves\nare derived and presented in the context of Frieze symmetry-groups. It is\nshown, for e…
