In a book that will generate both support and controversy, one of the world's foremost authorities on periodic structures addresses several of the current fashions in antenna design--most specifically, the popular subject of double negative metamaterials. Professor Munk provides a comprehensive theoretical electromagnetic investigation of the issues and concludes that many of the phenomena claimed by researchers may be impossible. While denying the existence of negative...

The idea of mixing single available materials into compounds to fulfill a set of desired properties is likely as old as mankind. Highly sophisticated polymer applications would simply be impossible without the enhancement of some of their properties through addition of fine mineral particles or synthetic or natural short fibers. Many filled polymers, either thermoplastics or vulcanizable rubbers, have different chemical natures but exhibit common singular properties. An understanding of why they do so is likely to be the source of promising scientific and engineering developments and...

Electromechanical Properties in Composites Based on Ferroelectrics investigates the problem of prediction and non-monotonicity of the effective electromechanical (piezoelectric, dielectric and elastic) properties in two- and three-component composites based on ferroelectric ceramics and relaxor-ferroelectric single crystals. The book analyzes the interrelations between the electromechanical constants of the components, and describes the different analytical schemes for averaging the properties of these materials with different connectivity and microgeometrical characteristics. The book...

The second of a three-volume series that aims to deliver a comprehensive account of the vast field of solid-state physics, this book goes far beyond most classic texts in the presentation of the properties of solids and experimentally observed phenomena.

The studies on Biohydrogels have had a rapid, exponential evolution in the last decades. Starting from one of the first applications of hydrogels in surgery, polyvinylalcohol crosslinked with formaldehyde under the trade name of Ivalon, we passed through PolyHema hydrogels as contact lens materials, hydrophilic polyurethanes (HPU), biodegradable hydrogels for both reconstructive surgery and pharmaceutical delivery systems, and finally more recently, one decade old, the thermoreversible and transient network hydrogels. Of course all these classes of hydrogels have been always and...

Spurred on by extensive research in recent years, organic semiconductors are now used in an array of areas, such as organic light emitting diodes (OLEDs), photovoltaics, and other optoelectronics. In all of these novel applications, the photoexcitations in organic semiconductors play a vital role. Exploring the early stages of photoexcitations that follow photon absorption, Ultrafast Dynamics and Laser Action of Organic Semiconductors presents the latest research investigations on photoexcitation ultrafast dynamics and laser action in pi-conjugated polymer films,...

This paper tries to give an overview on technologies using fibrous materials for contributing to environmental and resource matters. The technologies for water treatment include bio-reactive treatment system using membrane hollow fibre, desalination using Ro hollow fibre, purification of water work using UF or MF hollow fibre, purification of recycled water using photo-catalyst fibre, and oil removal systems using micro-fibre nonwoven. Removal system for incineration dust using bag filter, and removal system for toxic gas and solvent recovery using activated carbon fibre are typical...

Although there are many books available on the preparation, properties, and characterization of nanomaterials, few provide an interdisciplinary account of the physical phenomena that govern the novel properties of nanomaterials. Addressing this shortfall, Nanoscale Physics for Materials Science covers fundamental cross-disciplinary concepts in materials science and engineering. It presents a comprehensive description of the physical phenomena and changes that can be expected when macroscopically sized materials are reduced to the nanometer level.
