Download Microstrip filters for RF/microwave applications by Jia-Sheng Hong PDF

By Jia-Sheng Hong

The 1st variation of “Microstrip Filters for RF/Microwave purposes” was once released in 2001. through the years the e-book has been good bought and is used commonly in either academia and via microwave researchers and engineers.  From its inception as a manuscript the e-book is nearly eight years old.  whereas the basics of filter out circuits haven't replaced, extra techniques in filter out realizations and different functions have happened with alterations within the know-how and use of recent fabrication strategies, similar to the new advances in RF MEMS and ferroelectric movies for tunable filters; using liquid crystal polymer (LCP) substrates for multilayer circuits, in addition to the hot filters for dual-band, multi-band and extremely wideband (UWB) functions.

Although the microstrip filter out is still as the major transmission line medium for those new advancements, there has been a new pattern of utilizing mixed  planar transmission line buildings comparable to co-planar waveguide (CPW) and slotted floor constructions for novel actual implementations past the only layer so one can in achieving clear out miniaturization and higher performance.

Also, through the years, practitioners have steered themes that are meant to be additional for completeness, or deleted every so often, as they weren't very important in practice. 

In view of the above, the authors are providing a revised model of the “Microstrip Filters for RF/Microwave purposes” textual content and a marginally replaced e-book name of “Planar Filters for RF/Microwave functions” to mirror the aforementioned tendencies within the revised book.

Download Metamaterials for Perfect Absorption by Young Pak Lee, Joo Yull Rhee, Young Joon Yoo, Ki Won Kim PDF

By Young Pak Lee, Joo Yull Rhee, Young Joon Yoo, Ki Won Kim

This publication presents a finished assessment of the speculation and sensible improvement of metamaterial-based ideal absorbers (MMPAs). It starts off with a quick historical past of MMPAs which experiences a few of the theoretical and experimental milestones of their improvement. The theoretical historical past and primary operating rules of MMPAs are then mentioned, supplying the mandatory historical past on how MMPAs paintings and are built. There then follows a bit describing how varied MMPAs are designed and outfitted in accordance with the working frequency of the electromagnetic wave, and the way their habit is modified. tools of fabricating and characterizing MMPAs are then presented.

The ebook elaborates at the functionality and features of MMPAs, together with electromagnetically-induced transparency (EIT). It additionally covers fresh advances in MMPAs and their purposes, together with multi-band, broadband, tunability, polarization independence and occurrence independence.

Suitable for graduate scholars in optical sciences and digital engineering, it's going to additionally function a necessary reference for energetic researchers in those fields.

Download Digital Holography and Wavefront Sensing: Principles, by Ulf Schnars, Claas Falldorf, John Watson, Werner Jüptner PDF

By Ulf Schnars, Claas Falldorf, John Watson, Werner Jüptner

This e-book provides a self-contained therapy of the foundations and significant purposes of electronic hologram recording and numerical reconstruction (Digital Holography). This moment variation has been considerably revised and enlarged. The authors have prolonged the bankruptcy on electronic Holographic Microscopy to include new sections on particle sizing, particle snapshot velocimetry and underwater holography. a brand new bankruptcy now offers comprehensively and largely with computational wave box sensing. those suggestions signify a desirable replacement to plain interferometry and electronic Holography. they allow wave box sensing with no the requirement of a selected reference wave, hence permitting using low brilliance gentle resources or even liquid-crystal monitors (LCD) for interferometric applications.

Download Phase Noise and Frequency Stability in Oscillators (The by Enrico Rubiola PDF

By Enrico Rubiola

Providing a entire account of oscillator part noise and frequency balance, this sensible textual content is either mathematically rigorous and obtainable. An in-depth therapy of the noise mechanism is given, describing the oscillator as a actual procedure, and exhibiting that straightforward common legislation govern the steadiness of a giant number of oscillators differing in expertise and frequency variety. necessarily, precise recognition is given to amplifiers, resonators, hold up traces, suggestions, and flicker (1/f) noise. The opposite engineering of oscillators in accordance with phase-noise spectra can be lined, and end-of-chapter routines are given. Uniquely, quite a few useful examples are awarded, together with case stories taken from laboratory prototypes and advertisement oscillators, which permit the oscillator inner layout to be understood by means of reading its phase-noise spectrum. according to tutorials given by means of the writer on the Jet Propulsion Laboratory, overseas IEEE conferences, and in undefined, it is a important reference for tutorial researchers, practitioners, and graduate scholars in RF engineering and communications engineering.
