News as Culture
At the turn of the millennium, Indian journalism has undergone significant changes. The rapid commercialization of the press, together with an increase in literacy and political consciousness, has led to swift growth in the newspaper market but also changed the way news makers mediate politics. Positioned at a historical junction where India is clearly feeling the effects of market liberalization, this study demonstrates how journalists and informants interactively create new forms of political action and consciousness. The book explores English and Hindi newsmaking and investigates the creation of news relations during the production process and how they affect political images and leadership traditions. It moves beyond the news-room to outline the role of journalists in urban society, the social lives of news texts and the way citizens bring their ideas and desires to bear on the news discourse. This important volume contributes to an emerging debate about the impact of the media on Indian society. Furthermore, it convincingly demonstrates the inseparable link between media related practices and dynamic cultural repertoires.
Active Radar Cross Section Reduction
This book discusses the active and passive radar cross section (RCS) estimation and techniques to examine the low observable aerospace platforms. It begins with the fundamentals of RCS, followed by the dielectric, magnetic and metamaterials parameters of the constituent materials and then explains various methods and the emerging trends followed in this area of study. The RCS estimation of phased array including the mutual coupling effect is also presented in detail in the book. The active RCS reduction is carefully touched upon through the performance of phased arrays, sidelobe cancellers and mitigation of multipath effect. Providing information on various adaptive algorithms like least mean square (LMS), recursive least square (RLS) and weighted least square algorithms, the authors also mention the recent developments in the area of embedded antennas, conformal load bearing antenna, metamaterials and frequency selective surface (FSS) based RCS reduction.
AKASHVANI
"Akashvani" (English) is a programme journal of ALL INDIA RADIO, it was formerly known as The Indian Listener. It used to serve the listener as a bradshaw of broadcasting ,and give listener the useful information in an interesting manner about programmes, who writes them, take part in them and produce them along with photographs of performing artists. It also contains the information of major changes in the policy and service of the organisation. The Indian Listener (fortnightly programme journal of AIR in English) published by The Indian State Broadcasting Service, Bombay, started on 22 December, 1935 and was the successor to the Indian Radio Times in English, which was published beginning ...
Patna: A Paradise Lost!
Barring a few like Athens, Rome, Instanbul, Jeusalem and Damascus, not many big cities of modern world can boast of a 2500 year old history behind them. This book is a saga of the 2500 year long journey of Patna, its rise , decline and how she rose once again from a small port hamlet Pattan during Buddha to a fortress city at the time of great Magadhan king Ajatshatru which was later passed on to Chandragupta Maurya who converted this city into a marvelous magic in wood and brick with elegant palaces gates and watchtowers. Then came Ashoka who created the magnificent sixty-four pillared Mauryan Hall and a palace. This book takes you on the journey of this city from Ajastshatru to the Guptas ...

Electromagnetic Performance Analysis of Graded Dielectric Inhomogeneous Radomes
This book reports on a new radome wall configuration based on an inhomogeneous planar layer, which overcomes current fabrication constraints in radome design and yields improved electromagnetic (EM) characteristics. The book also includes a detailed description of radomes and antenna-radome interaction studies for different radome wall configurations. The radome wall was designed using the equivalent transmission line method (EQTLM), since it requires less computational speed and provides accurate results. In order to substantiate the accuracy of the results obtained using EQTLM, the simulated results based on full wave methods like CST Microwave Studio Suite are also included. The EM perfor...
Terahertz Antenna Technology for Space Applications
This book explores the terahertz antenna technology towards implementation of compact, consistent and cheap terahertz sources, as well as the high sensitivity terahertz detectors. The terahertz EM band provides a transition between the electronic and the photonic regions thus adopting important characteristics from these regimes. These characteristics, along with the progress in semiconductor technology, have enabled researchers to exploit hitherto unexplored domains including satellite communication, bio-medical imaging, and security systems. The advances in new materials and nanostructures such as graphene will be helpful in miniaturization of antenna technology while simultaneously maintaining the desired output levels. Terahertz antenna characterization of bandwidth, impedance, polarization, etc. has not yet been methodically structured and it continues to be a major research challenge. This book addresses these issues besides including the advances of terahertz technology in space applications worldwide, along with possibilities of using this technology in deep space networks.
Permittivity and Permeability Tensors for Cloaking Applications
This book is focused on derivations of analytical expressions for stealth and cloaking applications. An optimal version of electromagnetic (EM) stealth is the design of invisibility cloak of arbitrary shapes in which the EM waves can be controlled within the cloaking shell by introducing a prescribed spatial variation in the constitutive parameters. The promising challenge in design of invisibility cloaks lies in the determination of permittivity and permeability tensors for all the layers. This book provides the detailed derivation of analytical expressions of the permittivity and permeability tensors for various quadric surfaces within the eleven Eisenhart co-ordinate systems. These include the cylinders and the surfaces of revolutions. The analytical modeling and spatial metric for each of these surfaces are provided along with their tensors. This mathematical formulation will help the EM designers to analyze and design of various quadratics and their hybrids, which can eventually lead to design of cloaking shells of arbitrary shapes.
Plasma-based Radar Cross Section Reduction
This book presents a comprehensive review of plasma-based stealth, covering the basics, methods, parametric analysis, and challenges towards the realization of the idea. The concealment of aircraft from radar sources, or stealth, is achieved through shaping, radar absorbing coatings, engineered materials, or plasma, etc. Plasma-based stealth is a radar cross section (RCS) reduction technique associated with the reflection and absorption of incident electromagnetic (EM) waves by the plasma layer surrounding the structure. A plasma cloud covering the aircraft may give rise to other signatures such as thermal, acoustic, infrared, or visual. Thus it is a matter of concern that the RCS reduction ...
