Lumped Element Quadrature Hybrids

Quadrature hybrids are passive circuit components which are utilized in quite a lot of RF and microwave functions, and this state of the art booklet is the 1st source to supply engineers with a superior figuring out in their features and layout. The ebook is helping execs use lumped point quadrature hybrids to accomplish super large bandwidth operation.

RF The Rf And Microwave Circuit Design Cookbook

Within the fast moving, "I-need-it-done-by-yesterday" global of microwave engineering, it truly is extra very important than ever to get your circuit designs up-and-running on time and to necessities. Authored by way of a widely known professional within the undefined, this exact new ebook is helping you do exactly that by way of proposing no-nonsense, proven-under-fire microwave circuit layout "recipes" for you to keep on with for quick layout effects -- with no need to plow through pages of theoretical or educational rhetoric.

Multi-dimensional Optical Storage

This ebook offers ideas and purposes to extend the cupboard space from 2-D to 3D or even multi-D, together with grey scale, colour (light with varied wavelength), polarization and coherence of sunshine. those actualize the advancements of density, capability and knowledge move expense for optical information garage.
