Book Description

Na primeira década do século XXI, o pensamento e a produção da fotografia foram alterados pela disseminação das câmeras digitais, da circulação das imagens via internet e dos softwares de pós-produção. Assim, a fotografia ganhou crescente espaço nas grandes mostras de arte pelo mundo e no mercado de arte. Nossa cultura antropofágica mostrou-se um processo potente para gerar uma fotografia vibrante que passou a ser pesquisada e divulgada por curadores e instituições do mundo inteiro. Este livro de referência apresenta 52 expoentes brasileiros neste cenário. Este ebook traz imagens que são melhor visualizadas em tablets. In the first decade of this century, thought and photography production have been changed by the popularization of digital cameras, images shared through internet and post-production software. Thus, photography increased its space in the big world of art exhibitions and market. Brazilian anthropophagic culture proved to be a powerful process to create a vibrant photography production that became object of research and propagation by curators and institutions worldwide. This reference book presents 52 brazilian exponents of this scenario. This ebook contains images that are best viewed on tablets.

Resonant Scattering and Generation of Waves


Book Description

This monograph deals with theoretical aspects and numerical simulations of the interaction of electromagnetic fields with nonlinear materials. It focuses in particular on media with nonlinear polarization properties. It addresses the direct problem of nonlinear Electrodynamics, that is to understand the nonlinear behavior in the induced polarization and to analyze or even to control its impact on the propagation of electromagnetic fields in the matter. The book gives a comprehensive presentation of the results obtained by the authors during the last decade and put those findings in a broader, unified context and extends them in several directions.It is divided into eight chapters and three appendices. Chapter 1 starts from the Maxwell’s equations and develops a wave propagation theory in plate-like media with nonlinear polarizability. In chapter 2 a theoretical framework in terms of weak solutions is given in order to prove the existence and uniqueness of a solution of the semilinear boundary-value problem derived in the first chapter. Chapter 3 presents a different approach to the solvability theory of the reduced frequency-domain model. Here the boundary-value problem is reduced to finding solutions of a system of one-dimensional nonlinear Hammerstein integral equations. Chapter 4 describes an approach to the spectral analysis of the linearized system of integral equations. Chapters 5 and 6 are devoted to the numerical approximation of the solutions of the corresponding mathematical models. Chapter 7 contains detailed descriptions, discussions and evaluations of the numerical experiments. Finally, chapter 8 gives a summary of the results and an outlook for future work.
