Electromagnetic waves in layered nanoresonator systems including bi-isotropic and metamaterial layers: analytical model and characteristic features of proper waves

Reflection and transmission of nanoresonators including bi-isotropic and metamaterial layers: opportunities to control and amplify chiral and nonreciprocal effects for nanophotonics applications

“…We consider the interaction of an electromagnetic plane monochromatic wave with a layered system under oblique incidence [1]. A geometry of the multilayer and the corresponding electromagnetic boundary problem is illustrated in Figure 1.…”

“…The present paper is the second of two ones (the first is [1] where the detailed problem statement and general analytical model were discussed) devoted to the modeling of optical properties of the plane-layered nanoresonators including the main layer made of a bi-isotropic material or metamaterial (MM) sandwiched between pairs of dielectric, epsilon-near-zero (ENZ) or metallic spacer layers. Such one-dimensional nanometric systems (that are relatively easy to realize using modern thin film and nanocomposite technologies) demonstrate the optical properties that can be of interest for many nanophotonics applications.…”

“…[6][7][8][9][10] and numerous references in these papers) works in the field of chiral natural (gyrotropic) and artificial media. However, new opportunities, arising from the rapid development of electrodynamics and technology of electromagnetic MMs [1,[11][12][13][14][15][16][17][18][19][20][21], require further investigations and these opportunities are seemed to be very perspective for various applications of such media.…”

“…This paper uses the analytical model proposed in [1] and based on the accurate solution of the corresponding boundary electromagnetic problem for monochromatic waves, to investigate the features of reflected and transmitted radiation (the main properties of the proper waves inside of the system were considered in [1]). The present paper includes the detailed numerical and graphical analysis of the energy and polarization characteristics of the waves outside of the nanoresonator pointing to the new possibilities for applications of such systems as ultrathin polarization and phase converters, filters, modulators, metasurfaces and other components of nanophotonics devices.…”

“…The work has the following structure. For the sake of completeness, the brief problem statement, the analytical model description and main results from [1] (used for the numerical analysis in the present work) are given in Section 2. Main parameters and dependences for the numerical analysis are considered in Section 3.…”
