“…Metasurface (MS) can be described as a twodimensional counterpart of metamaterial that consists of structural elements having subwavelength size as compared with the wavelength λ of the incident wave [1,2]. Such structures are widely studied for possible application in controlling the propagation of electromagnetic and acoustic waves [1,2].…”

“…Such structures are widely studied for possible application in controlling the propagation of electromagnetic and acoustic waves [1,2]. Meanwhile, for the periodic magnetic structures, called also magnonic crystals (MC), the main interest, so far, was concentrated on investigation of propagation of spin waves with λ comparable with the structure period Λ because main attention was focused on the Bragg resonances appearing when Λ nλ{2 (n 1, 2, 3, .…”

Magnetostatic surface waves (MSSW) propagation in YIG films with "leaky" and "resonant" metasurfaces (MS) is studied. "Leaky" MS was fabricated by ion etching of the subwavelength periodic structure in YIG film surface while "resonant" MS was formed by placing the subwavelength periodic array of YIG stripes onto the plane YIG film. The effects of filtration and the dispersion properties of MSSW in such structures are discussed.

“…Being easier to design, model and implement [23][24][25], metasurfaces have rapidly gained traction as a major subfield in metamaterials research [26]. As quasi-optical devices, metasurfaces provide control of reflection and transmission across the spectrum [27], paving the way for advanced components such as flat lenses [25,28], thin polarizers [29,30], spatial or frequency filters [31], and holographic and diffractive elements [21,32,33].…”

Polarizability extraction of complementary metamaterial elements in waveguides for aperture modeling

We consider the design and modeling of metasurfaces that couple energy from guided waves to propagating wavefronts. This is a first step towards a comprehensive, multiscale modeling platform for metasurface antennas-large arrays of metamaterial elements embedded in a waveguide structure that radiates intro free-space-in which the detailed electromagnetic responses of metamaterial elements are replaced by polarizable dipoles. We present two methods to extract the effective polarizability of a metamaterial element embedded in a one-or two-dimensional waveguide. The first method invokes surface equivalence principles, averaging over the effective surface currents and charges within an element to obtain the effective dipole moments; the second method is based on computing the coefficients of the scattered waves within the waveguide, from which the effective polarizability can be inferred. We demonstrate these methods on several variants of waveguidefed metasurface elements, finding excellent agreement between the two, as well as with analytical expressions derived for irises with simpler geometries. Extending the polarizability extraction technique to higher order multipoles, we confirm the validity of the dipole approximation for common metamaterial elements. With the effective polarizabilities of the metamaterial elements accurately determined, the radiated fields generated by a metasurface antenna (inside and outside the antenna) can be found self-consistently by including the interactions between polarizable dipoles. The dipole description provides an alternative language and computational framework for engineering metasurface antennas, holograms, lenses, beam-forming arrays, and other electrically large, waveguide-fed metasurface structures.

“…Metalenses with applications in photonics (IR and visible wavelengths) are of our interest here, leaving to supplementary reviews the analysis of reflectarrays and array lenses for uses in low-frequency regimes [8]. Our purpose is then introducing the above-mentioned preliminary results but mainly focus on recent advances in the field, not thoroughly discussed yet.…”

In this chapter, a review of the recent advances in optical metalenses is presented, with special emphasis in their experimental implementation. First, the Huygens' principle applied to ultrathin engineered metamaterials is introduced for the purpose of giving curvature to the wavefront of free-space wave fields. Primary designs based on metallic nanoslits and holey screens occasionally with variant width are first examined. Holographic plasmonic lenses are also explored offering a promising route to realize nanophotonic components. More recent metasurfaces based on nano-antenna resonators, either plasmonic or high-index dielectric, are analyzed in detail. Furthermore, 2D material lenses in the scale of a few nanometers enabling the thinnest lenses to date are here considered. Finally, dynamically reconfigurable focusing devices are reported for creating a scenario with new functionalities.
