Available in PDF, EPUB and Kindle. Book excerpt: In this investigation the TMono cylindrical resonant cavity combiner is studied and characterized with the objective of improving the understanding of the design parameters of this microwave circuit. The study portion of the investigation involves presenting the fundamental theory of the cylindrical resonant cavity and coaxial diode circuits which make up a cylindrical resonant cavity combiner, the general modelling of two-port resonant cavities, and the equivalent circuit impedance relations of the Kurokawa combiner model (2) which has been widely used by researchers in this area. The objective of using this model was to examine its applicability to higher-order TMono mode combiners. The characterization section includes the passive two-port measurement of impedance transmission coefficient on a TM020 test combiner under various circuit conditions. A correlation between the measured and calculated impedance at a single coaxial line is presented and the results demonstrate that the Kurokawa model generally replicates the measured response. However, it is shown that there exists a relationship between the coupling coefficient at the cavity/ coaxial line interface and the number of coaxial lines which must be included in the Kurokawa model. The results of the transmission measurements indicate that to achieve maximum combining efficiency, a high unloaded cavity Q must be maintained (i.e. through the use of small coaxial lines) and that the microwave absorber characteristic impedance must be minimized without causing instability in operation with IMPATT diodes.

Download or read book Coplanar Waveguide Circuits Components and Systems written by Rainee N. Simons and published by John Wiley & Sons. This book was released on 2004-04-07 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: Up-to-date coverage of the analysis and applications of coplanar waveguides to microwave circuits and antennas The unique feature of coplanar waveguides, as opposed to more conventional waveguides, is their uniplanar construction, in which all of the conductors are aligned on the same side of the substrate. This feature simplifies manufacturing and allows faster and less expensive characterization using on-wafer techniques. Coplanar Waveguide Circuits, Components, and Systems is an engineer's complete resource, collecting all of the available data on the subject. Rainee Simons thoroughly discusses propagation parameters for conventional coplanar waveguides and includes valuable details such as the derivation of the fundamental equations, physical explanations, and numerical examples. Coverage also includes: Discontinuities and circuit elements Transitions to other transmission media Directional couplers, hybrids, and magic T Microelectromechanical systems based switches and phase shifters Tunable devices using ferroelectric materials Photonic bandgap structures Printed circuit antennas

Download or read book Ridge Waveguides and Passive Microwave Components written by J. Helszajn and published by IET. This book was released on 2000-06-30 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book collects much of Helszajn's work (formerly, Heriot-Watt University) and includes closed-form and finite element calculations of the propagation constant, attenuation and mode spectrum for the ridge waveguide, and power-current and power-voltage definitions of impedance. Circular polarization is also treated. Propagation properties where the waveguide has a dielectric filler are calculated. The treatment is then extended to more complex designs, including quadruple ridge waveguides with and without a gyromagnetic filler. The text includes descriptions of many of the passive devices which can be realized using these waveguides, including isolators, phase shifters, and circulators. c. Book News Inc.
Download or read book Power Scaling of Enhancement Cavities for Nonlinear Optics written by Ioachim Pupeza and published by Springer Science & Business Media. This book was released on 2012-05-08 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Enhancement cavities are passive optical resonators in which continuous-wave laser radiation or pulses of a frequency comb are coherently overlapped, allowing for a power and intensity scaling of up to several orders of magnitude. A prominent application is the table-top generation of bright, laser-like radiation in spectral regions where direct laser action is inefficient or not available at all, via intracavity nonlinear optical processes. However, to exploit the full capacity of this technique further progress is needed. This thesis covers central problems of enhancement cavities, such as finding limitations in scaling the circulating power, measuring cavity parameters with high accuracy, tailoring transverse modes and coupling out radiation generated in the cavity. Unprecedented intracavity laser powers were demonstrated, surpassing previous results by an order of magnitude. As an application, harmonics of the fundamental 1040-nm radiation up to the 21st order are generated. Besides reporting these fine experimental results, the thesis provides an excellent introduction into the physics of enhancement cavities, supported by more than 140 references.
