The focus of the present thesis is on two topics: the first is the interaction of surface plasmons and active media, and the second is acoustic metamaterials. These two seemingly different topics are connected by the notion that the negative material responses can lead to surface states. Surface plasmons are surface electromagnetic waves on metal surfaces, a consequence of negative permittivity. The study of active plasmonics is two fold: firstly, we study the surface plasmon amplification to compensate the intrinsic metal losses; secondly we study the enhanced spontaneous emission of emitters in excited state close to the metal surfaces. The concept of metamaterials---periodic composite structures with resonating element as a unit cell---is extended to acoustics. These acoustic metamaterials provide effective negative material responses and therefore the new surface states. We first propose a simple analytical method to obtain explicit expressions for surface plasmon polariton (SPP) dispersion, propagation length and critical gain required to overcome losses. A multiple quantum well structure is proposed to study SPP amplification accounting for SPP polarization, refractive index and temperature effects. In addition, we show that the emission of an optical emitter into various channels---surface plasmons, lossy surface waves and free radiation---can be precisely controlled by strategically positioning the emitters close to the metal surfaces. Next, we report a direct experimental evidence of stimulated emission of SPP at telecom wavelengths (1532 nm) in a SPP waveguide geometry using erbium doped phosphate glass. Together---the theoretical and experimental studies---these could provide a range of photonic devices; for example, nanolasers, surface plasmon amplifiers and efficient emitters. We investigate the acoustic analogue of electromagnetic metamaterials, and we report an ultrasonic metamaterial consisting of an array of subwavelength Helmholtz resonators that exhibits negative modulus. With the freedom of design that these acoustic metamaterials provide, we propose a new surface wave on an acoustic metamaterial with effective negative mass density. We further extend the concept of metamaterials to shear horizontal transverse waves. We provide a design of elastic metamaterial that exhibits effective negative mass density, and we finally show that pure shear surface elastic wave is possible with elastic metamaterials of negative shear modulus. We believe that this new class of acoustic and elastic metamaterials offers interesting applications like materials with dispersive properties, negative index and sub-diffraction limited imaging.

Metamaterials represent a new emerging innovative field of research which has shown rapid acceleration over the last couple of years. In this handbook, we present the richness of the field of metamaterials in its widest sense, describing artificial media with sub-wavelength structure for control over wave propagation in four volumes. Volume 1 focuses on the fundamentals of electromagnetic metamaterials in all their richness, including metasurfaces and hyperbolic metamaterials. Volume 2 widens the picture to include elastic, acoustic, and seismic systems, whereas Volume 3 presents nonlinear and active photonic metamaterials. Finally, Volume 4 includes recent progress in the field of nanoplasmonics, used extensively for the tailoring of the unit cell response of photonic metamaterials. In its totality, we hope that this handbook will be useful for a wide spectrum of readers, from students to active researchers in industry, as well as teachers of advanced courses on wave propagation.

About the book: This book is the first comprehensive review on acoustic metamaterials; novel materials which can manipulate sound waves in surprising ways, which include collimation, focusing, cloaking, sonic screening and extraordinary transmission. It covers both experimental and theoretical aspects of acoustic and elastic waves propagating in structured composites, with a focus on effective properties associated with negative refraction, lensing and cloaking. Most related books in the field address electromagnetic metamaterials and focus on numerical methods, and little (or no) experimental section. Each chapter will be authored by an acknowledged expert, amongst the topics covered will be experimental results on non-destructive imaging, cloaking by surface water waves, flexural waves in thin plates. Applications in medical ultrasound imaging and modeling of metamaterials will be emphasized too. The book can serve as a reference for researchers who wish to build a solid foundation of wave propagation in this class of novel materials.

Metamaterials, artificial electromagnetic media achieved by structuring on the subwave-length-scale were initially suggested for the negative index and superlensing. They became a paradigm for engineering electromagnetic space and controlling propagation of waves. The research agenda is now shifting on achieving tuneable, switchable, nonlinear and sensing functionalities. The time has come to talk about the emerging research field of metadevices employing active and tunable metamaterials with unique functionalities achieved by structuring of functional matter on the subwave-length scale. This book presents the first systematic and comprehensive summary of the reviews written by the pioneers and top-class experts in the field of metamaterials. It addresses many grand challenges of the cutting edge research for creating smaller and more efficient photonic structures and devices.

This book covers recent mathematical, numerical, and statistical approaches for multistatic imaging of targets with waves at single or multiple frequencies. The waves can be acoustic, elastic or electromagnetic. They are generated by point sources on a transmitter array and measured on a receiver array. An important problem in multistatic imaging is to quantify and understand the trade-offs between data size, computational complexity, signal-to-noise ratio, and resolution. Another fundamental problem is to have a shape representation well suited to solving target imaging problems from multistatic data. In this book the trade-off between resolution and stability when the data are noisy is addressed. Efficient imaging algorithms are provided and their resolution and stability with respect to noise in the measurements analyzed. It also shows that high-order polarization tensors provide an accurate representation of the target. Moreover, a dictionary-matching technique based on new invariants for the generalized polarization tensors is introduced. Matlab codes for the main algorithms described in this book are provided. Numerical illustrations using these codes in order to highlight the performance and show the limitations of numerical approaches for multistatic imaging are presented.
