Metasurfaces: a new look at Maxwell’s equations and new ways to control light

Abstract

The basic principles of light controling by means of metasurfaces are reviewed. Metasurfaces are able to control the phase, amplitude, polarization, and frequency of radiation propagating through them. The formulation of the generalized Snell’s law is presented. Ways to realize metasurfaces using resonances and the methods of phase shift within 2 π are discussed. An overview of experiments and recent achievements in the field of the light controling by means of the metasurfaces is also presented. Possible applications of metasurfaces and further development of this paradigm are considered, too.

Features of transmission of electromagnetic waves through composite nanoresonators including epsilon-near-zero metamaterials

“…The expressions for quantities A ± , D ± (Eqs. (A1), (A4)) are also true for equations (9) and (10). The relations for the parameters in equations (A1)-(A10) are given in the main text.…”

“…( 18) with account of the opposite waves interference) has the values I TM (1) < 1 (values of I TM (1) (z = d 1 + 0.5d 2 ) are given in Figs. 9,10). This condition points to the conservation of the energy fluxes balance in the main layer.…”

“…1). So, the exact solutions of the boundary problems are determined by equations ( 7)- (10). Let us note that quantities t T M;T E 1;2 in equations ( 7)-( 10) characterize relations of the corresponding components of field E.…”

“…The progress in theory and technologies of nanophotonics, plasmonics, optics of metamaterials (MMs) and metasurfaces provided possibilities to reduce dimensions of many optical elements such as modulators, filters, absorbers, phase shifters, holograms, nanoresonators and others down to nanometer values (see, e.g. recent reviews [1][2][3][4][5][6][7][8][9][10][11][12] and numerous references in these works). The main purpose of such ultra-small devices is to control the radiation characteristics (amplitude, phase, polarization) at deeply subwavelength dimensions of a composite material or system.…”

“…In an isotropic medium, the solution of the system of Maxwell's equations [3,4] for the projections of the components of a plane electromagnetic wave that vary with time t in a Cartesian coordinate system (x, y, z), (1) can be written in the form: (2) where . If both ε and μ are positive, then the vectors E, H and k form a right-handed system of vectors.…”
