“…Metasurfaces (MTSs) are composed of a dense layer of subwavelength metallic elements, also called pixels [1][2][3], printed on top of a grounded substrate. Bounded slow surface waves (SWs) can be guided on these structures with engineered dispersion properties.…”

Dispersion Properties of an Elliptical Patch with Cross-Shaped Aperture for Synchronized Propagation of Transverse Magnetic and Electric Surface Waves

This paper presents a novel pixel geometry for the implementation of metasurfaces requiring synchronized phase propagation of transverse magnetic (TM) and transverse electric (TE) modes. The pixel is composed by an elliptical metallic patch with an asymmetric cross-shaped aperture in the center, printed on a grounded slab. A practical implementation of a metasurface was carried out employing such a pixel geometry. Simulation results show similar frequency dispersion properties for both modes within the working frequency band, in agreement with the theoretical basis.

“…1. The use of a printed EBG-type surface to convert surface waves into leaky waves has been recently applied in [4] with reference to holographic concepts. The so-called holographic antennas present a modulated high impedance surface as dictated by an interference pattern between the wave radiated by a feeder and a plane wave coming from a chosen direction of maximum radiation.…”

Maci, Fellow, IEEE Abstract-This letter proposes a new topology of antenna based on the use of planar circularly symmetric electromagnetic band gap (PCS-EBG) with different periodicities. These periodicities are used to impose different propagation velocities of the dominant surface waves on different zones of the same dielectric substrate. The control of the dispersion characteristics guides the design together with the definition of a centered feed suitable to excite the surface waves. One prototype has been designed, manufactured and tested to prove the concept.Index Terms-Leaky-wave antennas, millimeter-wave antennas, printed dipoles.

“…This control can be extended to surfaces through the use of tensor transmission-line metamaterials. The design approach will find use in the development of a wide range of electromagnetic devices including antennas and beam-forming networks, and may also find application in scattering control [58,59] and holography [60,61]. It could provide a novel approach to signal routing, the design of mode conversion devices [62], and the generation of extreme antenna apertures for super-directive radiation [63] or the excitation of Airy [64][65][66][67] and Bessel beams [68][69][70][71].…”

PLEASE DO NOT RETURN YOUR FORM TO THE ABOVE ADDRESS. REPORT DATE (DD-MM-YYYY)2 None Near-field plates and their potential uses were theoretically and experimentally investigated under this grant. Near-field plates are subwavelength-textured surfaces that can focus electromagnetic fields to deep subwavelength resolutions. Their operation was theoretically explained, design methodologies were formulated, and several prototypes developed at microwave frequencies. This research effort also included a second objective. The second objective was rather broad: to arbitrarily control electromagnetic fields within a 2D region of space using anisotropic and inhomogeneous metamaterials. This effort involved the development of circuit-based metamaterials that exhibit tensorial effective material parameters, and the implementation of electromagnetic devices using such metamaterials. It also involved the development of synthesis methods for anisotropic and inhomogeneous two dimentional (2D) metamaterials.metamaterials, metasurfaces, near-field plates, anisotropic and inhomogeneous materials.Anthony Grbic
