“…It is wellknown that these are not independent of each other, and hence it is possible to formulate electrodynamics of media as a single susceptibility theory [29], where all linear electromagnetic response functions are derived from a single response tensor. For example, in magneto-optics it has been suggested to introduce an effective permittivity tensor relating the D and E fields while setting H = B/µ 0 identically [61][62][63]. By contrast, here we stick to the usual definition of electromagnetic response functions and relate each of them to the microscopic conductivity tensor, a possibility which has already been mentioned in Ref.…”

In this article, we put forward a new approach to electrodynamics of materials. Based on the identification of induced electromagnetic fields as the microscopic counterparts of polarization and magnetization, we systematically employ the mutual functional dependencies of induced, external and total field quantities. This allows for a unified, relativistic description of the electromagnetic response without assuming the material to be composed of electric or magnetic dipoles. Using this approach, we derive universal (material-independent) relations between electromagnetic response functions such as the dielectric tensor, the magnetic susceptibility and the microscopic conductivity tensor. Our formulae can be reduced to well-known identities in special cases, but more generally include the effects of inhomogeneity, anisotropy, magnetoelectric coupling and relativistic retardation. If combined with the Kubo formalism, they would also lend themselves to the ab initio calculation of all linear electromagnetic response functions.

“…It is worth mentioning that these are general considerations which guarantee that the PPEs associated to this kind optical fiber may describe the propagation of pulses in a large gamut of single-core fibers: classical weakly-guiding fibers, optical gain fibers (amplification can be regarded as negative absorption, as mentioned before), polarization-maintaining fibers, highlynonlinear fibers and photonic crystal fibers. In addition, all-magnetic fibers [34], [35] can also be described by the same PPEs as those of the all-dielectric case (see page 14 of Supplementary Material).…”

The comprehension of pulsed light propagation is of paramount importance in fiber optics. Here, we present a general method to describe the propagation of pulses in any kind of optical fiber, regardless of its fabrication process or constituent materials. As a result, we obtain a rich toolbox for the analysis and synthesis of optical fibers, which allows us to circumvent the resolution of Maxwell's equations by using heavy-computational numerical methods. To illustrate this, we analyze the pulse propagation problem in nonparaxial anisotropic single-core and multi-core fibers that cover a large variety of optical fibers including classical weakly guiding fibers, optical gain fibers, polarization-maintaining fibers, highly nonlinear fibers, and photonic crystal fibers. Moreover, it is shown that our method can be applied to any kind of guided and unguided medium undergoing spatial and temporal perturbations, provided that the distance and temporal width between different consecutive spatial and temporal medium perturbations are respectively higher than the spatial and temporal width of the optical pulses.

“…The study of these structures lasts several decades, they find their application as microwave technology devices, planar waveguide structures and lasers, magneto-optical devices and visual magnetometer sensors, etc. [1][2][3]. Performances of these structures are determined by properties of the surface layer of functional films with the thickness less than one micrometer, which allows its modification by postgrowth processing.…”

The scattering field gradient maps of surface layer magnetic domains in Y 2.95 La 0.05 Fe 5 O 12 iron-yttrium garnet modified by high-dose ion implantation with nitrogen ions N + were obtained by the method of magnetic force microscopy. It was found that improving the magnetic properties of thin films, which includes reducing the observed magnetic losses after high-dose implantation, is accompanied by essential ordering of magnetic domains on the surface of the implanted films. There is a direct dependence of the magnetic properties on the dose of implanted atoms, accompanied by a significant dispersion and amorphization of surface layer and formation of a clear magnetic structure.
