Asymptotic Methods in Electromagnetics

By: Daniel Bouche,Frederic Molinet,Raj Mittra

Numerically rigorous techniques for the computation of electromagnetic fields diffracted by an object become computationally intensive, if not impractical to handle, at high frequencies and one must resort to asymptotic methods to solve the scattering problem at short wavelengths. The asymptotic methods provide closed form expansions for the diffracted fields and are also useful for eliciting physical interpretations of the various diffraction phenomena. One of the principal objectives of this book is to discuss the different asymptotic methods in a unified manner. Although the book contains explicit formulas for computing the field diffracted by conducting or dielectric-coated objects, it also provides the mathematical foundations of the different methods and explains how they are interrelated.

FDTD Modeling of Metamaterials: Theory and Applications

By: Yang Hao,Raj Mittra

Master powerful new modeling tools that let you quantify and represent metamaterial properties with never-before accuracy. This first-of-its-kind book brings you up to speed on breakthrough finite-difference time-domain techniques for modeling metamaterial characteristics and behaviors in electromagnetic systems. This practical resource comes complete with sample FDTD scripts to help you pave the way to new metamaterial applications and advances in antenna, microwave, and optics engineering. You get in-depth coverage of state-of-the-art FDTD modeling techniques and applications for electromagnetic bandgap (EBG) structures, left-handed metamaterials (LHMs), wire medium, metamaterials for optics, and other practical metamaterials. You find steps for computing dispersion diagrams, dealing with material dispersion properties, and verifying the left-handedness. Moreover, this comprehensive volume offers guidance for handling the unique properties possessed by metamaterials, including how to define material parameters, characterize the interface of metamaterial slabs, and quantify their spatial as well as frequency dispersion characteristics. The book also presents conformal and dispersive FDTD modeling of electromagnetic cloaks, perfect lens, and plasmonic waveguides, as well as other novel antenna, microwave, and optical applications. Over 190 illustrations support key topics throughout the book.

Decolonised and Developmental Social Work

A Model from Nepal

By: Raj Yadav

This is the first book to cover existing debates on decolonising and developmental social work whilst equipping readers with the understanding of how to translate the idea of decolonisation of social work into practice. Using new empirical data and an extensive detail of social, cultural, and political dimensions of Nepal, the author proposes a new model of ‘decolonised and developmental social work’ that can be applicable to a wide range of countries and cultures. By using interviews with Nepali social workers, this text goes beyond mere theoretical approaches and uniquely positions itself in a way that embraces rigorous bottom-up, grounded theory method. It will also further ongoing debates on globalisation-localisation, universalisation-contextualisation, outsider-insider perspectives, neoliberal-rights and justice oriented social work, and above all, colonisation-decolonisation of social work knowledge and practice. It also promotes solidarity of, and the struggle for, progress for those in the margins of Western social work and development narrative through an emerging theory-praxis of decolonised and developmental social work. Decolonised and Developmental Social Work is essential reading for students, academics, and researchers of social work and development studies, as well as those striving for a decolonial worldview.
