Gigabit Wireless at 60 GHz
ISBN: 9783838335025 / Angielski / Miękka / 228 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The world-wide availability of the huge amount of license-free spectral space in the 60 GHz band provides wide room for Gb/s wireless applications. A commercial (read: low-cost) 60-GHz transceiver will, however, provide limited system performance due to the stringent link budget and the substantial RF imperfections. This book comprises research into the characteristics of typical 60-GHz channels, the influence of directional antenna patterns, the evaluation of the wideband transmission quality as well as the development of suitable baseband algorithms in the context of 60-GHz radios. A...

Bi2Sr2CaCu2O8+x React Wind Sinter Experiments
ISBN: 9783838300269 / Angielski / Miękka / 64 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Manufacturing solenoids from Ag-clad Bi2Sr2CaCu2O8+x (Bi2212) conductors is complicated by the difficult thermo-mechanical processing. The two approaches usually used for winding coils are React-and-Wind (R&W) and Wind-and-React (W&R). React Wind Sinter (RWS) presents two alternative approaches that avoid the pitfalls of R&W and W&R. In the first RWS approach, the conductor is taken through the partial melt stage of the heat treatment, cooled to room temperature, and wound into its final coil form. It is then taken through growth and sinter steps to complete the heat treatment and heal...

Light Propagation in Ultracold Atomic Gases
ISBN: 9783838372662 / Angielski / Miękka / 140 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Laser and atomic gases allow to study radiation-matter interaction at its fundamental level. After the development of laser sources, atomic gases have been successfully used to study non-linear processes. Later on, light has been demonstrated as a very powerful tool not only to study atoms but also to manipulate them. The achievement of ultracold gases (1997 and 2001 Nobel prizes) is the most remarkable among many. Starting from an optical point of view, we theoretically investigate the features of ultracold atomic gases as an extremely dispersive and tunable medium. We first discuss the...

Effect of Induction on Capacitor Bank Protection Schemes
ISBN: 9783843350884 / Angielski / Miękka / 84 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Overall, capacitors have many applications in power systems: they can be used in series to compensate the inductance of transmission lines to transmit more power. They can also be used as surge capacitors, starting motors, and SVC. Capacitor banks installed in power substations are vital in the sense that they provide the reactive power needed for the power system, which in turn improves the voltage profile of the system. There is always the option of grounding the banks or leaving them ungrounded. Each of the above configurations has its own advantages and disadvantages; to name a...

Tunable Microcavities in Photonic Bandgap Yarns and Optical Fibers
ISBN: 9783843361644 / Angielski / Miękka / 148 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The vision behind this work is the fabrication of high performance innovative fiber-based optical components over kilometer length-scales. Their optical properties derive from their multilayer dielectric photonic band-gap structure that exhibits omnidirectional reflectivity. The theoretical tools needed to design, analyze and optimize such structures are introduced. We show that defect layers in these otherwise periodic structures act as micro-cavities that enable precise design of the fibers spectral response. Two structures are explored: fibers for external reflection and hollow-...

Metamaterials in a Mobile Phone
ISBN: 9783844306071 / Angielski / Miękka / 116 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This thesis focuses on the use of metamaterials in mobile phone devices in order to improve antenna performances, e.g. to investigate if they can reduce the peak of SAR in the human head. The purpose is to present metamaterials in a general way as many researches do not provide general background and knowledge, and focus on very specific uses and topics. As many researches focus on the use of metamaterials with antennas, the second objective is to analyze if they could possibly improve the performances of antennas. Thanks to FDTD simulations, several configurations have been investigated. The...

Thermoelectricity: Thermoelectric and Thermomagnetic Properties in Low-Dimensional and Nanoscale Materials
ISBN: 9781846283628 / Angielski / Twarda / 4 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Thermoelectricity describes the physics of energy conversion, from heat to electric power, and from electric power to heat or cooling power in solids. The working fluid consists of the conduction electrons. While this classical subject has a long and distinguished history, very recent developments in nanotechnologies have revolutionized the field. It was recognized in the 1990s that low-dimensional systems should result in materials with much better efficiencies than bulk materials, through low-dimensional effects on both charge carriers and lattice waves. Such improvements have... Thermoelectricity describes the physics of energy conversion, from heat to electric power, and from electric power to heat or cooling power in soli... |

Classical and Quantum Approach of Quasi Normal Modes in Linear Regime
ISBN: 9783838391939 / Angielski / Miękka / 180 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The definition of natural modes for confined structures is one of the central problems in physics, as in nuclear physics, astrophysics, etc. The main problem is due to the boundary conditions, when they are such to push out the problem from the class of Sturm-Liouville. This occurs when boundary conditions imply the presence of eigen-values, as for example when a scatterer excited from the outside gives rise to a transmitted and reflected field. An open cavity with an external or internal excitation represents a "non-canonical" problem, in the sense of a Sturm-Liouvilles problem, due to the...
