By Dr. Yong Zhang, Angelo Mascarenhas (auth.), Dr. Clifford M. Krowne, Dr. Yong Zhang (eds.)

This publication bargains with the topic of optical and digital damaging refraction (NR) and unfavourable index fabrics NIM). various methods for attaining NR and NIM are coated, corresponding to utilizing photonic crystals, phononic crystals, split-ring resonators (SRRs) and non-stop media, focusing of waves, guided-wave habit, and nonlinear results. particular issues taken care of are polariton thought for LHMs (left passed materials), focusing of waves, guided-wave habit, nonlinear optical results, magnetic LHM composites, SRR-rod realizations, low-loss guided-wave bands utilizing SRR-rods unit cells as LHMs, NR of electromagnetic and digital waves in uniform media, box distributions in LHM guided-wave constructions, dielectric and ferroelectric NR bicrystal heterostructures, LH metamaterial photonic-crystal lenses, subwavelength focusing of LHM/NR photonic crystals, focusing of sound with NR and NIMs, and LHM quasi-crystal fabrics for focusing.

Introduction to Solid State Physics

Re-creation of the main widely-used textbook on sturdy country physics on this planet. Describes how the excitations and imperfections of exact solids should be understood with basic versions that experience firmly tested scope and tool. the root of this booklet is predicated on scan, software and idea.

Introduction to General Relativity

Basic relativity is a gorgeous scheme for describing the gravitational fieldan dth equations it obeys. these days this conception is frequently used as a prototype for different, extra difficult structures to explain forces among undemanding debris or different branches offundamental physics. this is because in an advent to basic relativity it really is of significance to split as essentially as attainable a number of the parts that jointly provide form to this paradigm.

Electronic Structure and Physical Properties of Solids: The Uses of the LMTO Method

A truly complete booklet, permitting the reader to appreciate the elemental formalisms utilized in digital constitution selection and especially the "Muffin Tin Orbitals" tools. the most recent advancements are provided, delivering a really unique description of the "Full capability" schemes. This publication will supply a true cutting-edge, seeing that just about all of the contributions on formalism haven't been, and won't be, released in other places.
