Book Description
Metamaterials have experienced a rapid growth of interest over the past few years and new capabilities are being explored to broaden the range of their unique electromagnetic properties for functional devices, including tunable, switchable, and nonlinear properties. In the future, there is the prospect of opening even more exciting applications with metamaterials, not yet imagined and thought not to be possible with currently available techniques. In my dissertation, I discuss several solutions for passive and active metamaterials and metasurfaces, with a particular focus on their potential applications, enabling a new class of metamaterials in the spectral range from radio frequencies (RF) and microwaves, terahertz (THz) to visible light. First, I demonstrate that by loading plasmonic nanoantennas with nonlinear nanoparticles, the nonlinear optical processes, such as multiple wave mixing, high harmonic generation, phase conjugation and optical bistability may be realized at the nanoscale, thanks to the strongly enhanced optical near fields accompanied with the plasmonic resonance. I present here the design, practical realization, and homogenization theory of nonlinear optical metamaterials and metasurfaces formed by optical nanoantenna arrays loaded with nonlinearities. As an extreme case of light manipulation at the "atomic" scale, I also study the collective oscillation of massless Dirac fermions inside grapheme monolayers, in which surface plasmon polaritons are controlled by electrostatic gating. I present how a graphene monolayer may serve as a building block and design paradigm for adaptable, switchable and frequency-configurable THz metamaterials and nanodevices, realizing various functionalities for cloaking, sensing, absorbing, switching, modulating, phasing, filtering, impedance transformation, photomixing and frequency synthesis in the THz spectrum. Last I present various metamaterial designs applied to invisibility cloaks based on the scattering cancellation mechanism enabled by plasmonic materials and passive/active metamaterials and metasurfaces. This cloaking technology may be used for camouflaging, enhancing the sensitivity and signal-to-noise ratio in RF wireless communication and sensor networks. In addition, electrically-small antennas based on the phase compensation effect offered by metamaterials with low or negative material properties are presented, with tailorable modal frequencies, bandwidth, and radiation properties.

Book Description
Metamaterials have attracted enormous interests from both physics and engineering communities in the past 20 years, owing to their powerful ability in manipulating electromagnetic waves. However, the functionalities of traditional metamaterials are fixed at the time of fabrication. To control the EM waves dynamically, active components are introduced to the meta-atoms, yielding active metamaterials. Recently, a special kind of active metamaterials, digital coding and programmable metamaterials, are proposed, which can achieve dynamically controllable functionalities using field programmable gate array (FPGA). Most importantly, the digital coding representations of metamaterials set up a bridge between the digital world and physical world, and allow metamaterials to process digital information directly, leading to information metamaterials. In this Element, we review the evolution of information metamaterials, mainly focusing on their basic concepts, design principles, fabrication techniques, experimental measurement and potential applications. Future developments of information metamaterials are also envisioned.

Book Description
Nonlinear active metamaterial surfaces are constructed of planar periodic engineered structures in the sub-wavelength (lambda/4) scale on which the nonlinear circuit components have been populated. Unusual electromagnetic properties of the metamaterials derived by the resonant behavior of the constitutive unit cells have produced remarkable effects such as negative index of refraction, cloaking, and an electromagnetic band gap due to high impedance, while the implementations are restricted in bandwidth and polarization. The added nonlinearity from the nonlinear components can give the degree of freedom to achieve the unique and useful functionalities which could not be realized with linear and passive metamaterials. This thesis studies the theory, characterization, and capability of nonlinear active metasurfaces. The primary application of the invented metasurfaces is focused on exploring a new type of microwave absorbing structure, and the other unique electromagnetic properties. The state-of-the-art nonlinear circuits deployed on the metasurface offer the adaptive capabilities to tune the inherited electromagnetic properties. First, the theoretical limitations of the linear lossy coating are addressed to establish the necessity for the need for advanced absorbing structures. Subsequent chapters introduce the invented nonlinear metasurfaces with the different tunabilities, specifically the switchable metasurfaces that selectively absorb high power signals to avoid destructive interference to sensitive electronic devices. The self-tuning metasurfaces adaptively tune the resonance frequencies to match the frequencies of the incident waves for broadband absorbing bandwidth. The reconfigurable impedance surface has octave tunability maintaining the artificial magnetic conductor property to support an extreme broadband antenna system, and the omni-directional metamaterial surface to response all-directional incoming waves to minimize unexpected scattering effects in oblique angles.
