Microwave ring circuits and related structures
1 online resource (xii, 365 pages : : illustrations.)
Drawing on the dissertations, theses, and many papers by graduate students, research associates, and visiting scholars as well as on their own findings and that of colleagues, Chang and Hsieh (both electrical engineering, Texas A&M U.) introduce students and engineers to the analysis and models of the ring resonators and their application to filters, antennas, oscillators, couplers, and other devices. No date is cited for the first edition. The second considers ring resonators built in various transmission lines such as microstrip, slotline, coplanar waveguide, and waveguide. It also updates and sometimes corrects the previous discussions and incorporates recent applications. Annotation: 2004 Book News, Inc., Portland, OR (booknews.com).
