  • The passive components used in electronic circuits all make use of one or more of the three fundamental phenomena of resistance, capacitance and inductance. Some components depend for their operation on the interaction between one of these electrical properties and a mechanical property, e.g. crystals used as frequency standards, piezo-electric sounders, etc. The following sections look at components particularly in the light of their suitability for use at RFs, and at how they can be inter-connected for various purposes....

  • Temperature measurement and control are vital in many industrial processes. Accurate control of the temperature is essential in nearly all chemical processes. In some applications, an accuracy of around 5-10~ may be acceptable. There are also some industrial applications which require better than 4-1 ~ accuracy.

  • Various Components and Their System Parameters An RF and microwave system consists of many different components connected by transmission lines. In general, the components are classified as passive components and active (or solid-state) components. The passive components include resistors, capacitors, inductors, connectors, transitions, transformers, tapers, tuners, matching networks, couplers, hybrids, power dividers=combiners, baluns, resonators, filters, multiplexers, isolators, circulators, delay lines, and antennas. ...

  • Over many years, RF-MEMS have been a hot topic in research at the technology and device level. In particular, various kinds of mechanical Si-MEMS resonators and piezoelectric BAW (bulk acoustic wave) resonators have been developed. The BAW technology has made its way to commercial products for passive RF filters, in particular for duplexers in RF transceiver front ends for cellular communications. Beyond their use in filters, micromachined resonators can also be used in conjunction with active devices in innovative circuits and architectures.

  • Most antenna engineers are likely to believe that antennas are one technology that is more or less impervious to the rapidly advancing semiconductor industry. However, as demonstrated in this lecture, there is a way to incorporate active components into an antenna and transform it into a new kind of radiating structure that can take advantage of the latest advances in analog circuit design

  • Modelling and computations in electromagnetics is a quite fast-growing research area. The recent interest in this field is caused by the increased demand for designing complex microwave components, modeling electromagnetic materials, and rapid increase in computational power for calculation of complex electromagnetic problems. The first part of this book is devoted to the advances in the analysis techniques such as method of moments, finite-difference time- domain method, boundary perturbation theory, Fourier analysis, mode-matching method, and analysis based on circuit theory....

  • Expanders are an essential component of leadracid batteries. They prevent performance losses in negative plates that would otherwise be caused by passivation and structural changes in the active material. The functions of the components of modern negative-plate expanders are described and data are presented to show how the capacity and life of the battery are affected by the type and amount of barium sulfate and lignin incorporated in the expander blend.

  • Physiology of Circadian Rhythmicity The sleep-wake cycle is the most evident of the many 24-h rhythms in humans. Prominent daily variations also occur in endocrine, thermoregulatory, cardiac, pulmonary, renal, gastrointestinal, and neurobehavioral functions. At the molecular level, endogenous circadian rhythmicity is driven by self-sustaining transcriptional/translational feedback loops (Fig. 28-2). In evaluating a daily variation in humans, it is important to distinguish between those rhythmic components passively evoked by periodic environmental or behavioral changes (e.g.

  • Microseismic (passive) seismic monitoring was conducted at Weyburn to monitor the dynamic response of the reservoir rock matrix to CO2 injection (i.e., stress release due to injectioninduced deformation) and assess the level of induced seismicity in regard to safety of existing surface infrastructure and as an alternative means of mapping the spread of CO2 within the reservoir. An array of eight, three-component geophones was permanently installed just above the oil reservoir, which is located at approximately 1,450-meter depth.
