“…The concept of microwave holography or holographic antenna was first demonstrated by Checcacci, Russo and Scheggi in 1970 [39]. Microwave holographic antennas have been widely investigated in the past decades [40]. Typically, microwave holographic antennas typically comprise a main surface-wave-carrying impedance surface, which is separated from the ground plane by a dielectric slab.…”

“…Typically, microwave holographic antennas typically comprise a main surface-wave-carrying impedance surface, which is separated from the ground plane by a dielectric slab. Such an impedance surface can be designed to serve as a guiding structure or to support leaky waves, depending on the eigenmodes of the surface-wave structure and/or the modulation period and depth of equivalent surface impedance [39][40][41][42][43][44][45][46]. The pattern of surface perturbations and spatial profile of surface impedance can be designed by a "holography" method [41].…”

In this chapter, we will review recent research advances on beamforming and spatial multiplexing techniques using reconfigurable metamaterials (MTMs) and metasurfaces. This chapter starts by discussing basic principles and practical applications of transmission line-based metamaterials and planar metasurfaces, followed by their active versions that enable novel smart antennas with beam steering and beamshaping functions. We include detailed descriptions of their practical realizations and the integration with circuits and the radio-frequency (RF) frontend, which are used to adaptively and dynamically manipulate electromagnetic radiation. We summarize the state-of-the-art MTM/metasurface-based beamforming techniques and provide a critical comparison for their uses in the RF-to-millimeter-wave range in terms of cost, reconfigurability, system integratability and radiation properties. These techniques are expected to pave the way for the massive deployment of communication, radar, remote sensing and medical and security imaging systems.

The paper proposed a two dimensional (2D) electrical conductivity model based on the solid state plasma concentration distribution model. The results indicated that the imaginary part of the electrical conductivity is more sensitive to the electromagnetic signal frequency than the real part. And the real part is mainly effected by the internal properties of the solid state plasma. Finally, a smart solid state plasma dipole antenna is designed to test the effect of the imaginary part of the electrical conductivity on the radiation characteristics of the antenna. Plasma dipole antenna has also been compared with metal dipole antenna, the results show that the plasma antenna is entirely possible to replace the metal antenna.

“…Presently, there are some research groups studying antennas based on this principle, recognizing new opportunities holographic surfaces offer in the field of antennas [2]- [5]. One practical way to realize such a structure consists of the modulation of surface reactance, allowing the radiation of the fundamental mode of the structure, which otherwise is bounded.…”

A novel type of surface-impedance modulation mechanism for designing of microstrip-technology-based surface-waveexcited holographic antennas is proposed. The advanced radiating geometry consists of quasi-periodic arrangement of unit cells operating in the leaky-wave region. Flexible design requires a considerable numerical effort determining the dispersion characteristics of any possible unit cell present in the geometry. In this context, an analytic determination of the dispersion diagram for a unit cell with a sinusoidal modulation of the effective dielectric constant in its inside is presented. In this particular case, the solution is expressed in terms of Mathieu functions. The good agreement between numerical data and analytic solutions for an open, unbounded microstrip structure allows introducing the principle of a novel type of holographic surface obtained by cascading unit cells with different modulation parameters, where the phase of the radiating field can be geometrically controlled.
