The writer starts off with an introductory bankruptcy devoted to the basics of planar transmission traces. bankruptcy 2 is targeted on man made transmission strains in response to periodic buildings (including non-uniform transmission strains and reactively-loaded lines), and offers a complete research of the coupled mode thought. Chapters three and four are devoted to man made transmission traces encouraged through metamaterials, or in line with metamaterial thoughts. those chapters comprise the most useful implementations of such strains and their circuit types, and a large evaluation in their RF/microwave purposes (including passive and energetic circuits and antennas). bankruptcy five makes a speciality of reconfigurable units in line with tunable man made strains, and on non-linear transmission traces. The bankruptcy additionally introduces a number of fabrics and elements to accomplish tuning, together with diode varactors, RF-MEMS, ferroelectrics, and liquid crystals. eventually, bankruptcy 6 covers different complex transmission strains and wave guiding buildings, equivalent to electroinductive-/magnetoinductive-wave strains, common-mode suppressed balanced traces, lattice-network man made traces, and substrate built-in waveguides.
Artificial Transmission traces for RF and Microwave functions presents an in-depth research and dialogue of synthetic transmission traces, together with layout instructions that may be precious to researchers, engineers and students.
