Comprehensive resource presenting the fundamentals and state of the art concepts, design examples, relevant components, and technology.
Slow-wave Microwave and mm-wave Passive Circuits presents the fundamentals and state of the art concepts, design examples, relevant components, and technology of the subject, plus examples of circuit layout optimization using slow-wave circuits. Recent advances in aspects of the slow-wave concept are covered, with potential applications including automotive radars, medical and security applications, and 5G and future 6G for very high-speed communications.
The text considers a variety of slow-wave structures and associated concepts which are useful for circuit design, each structure electrically modeled with clear illustration.
The highly qualified authors show that the use of the slow-wave concept can, in some cases, improve the performance of passive circuits. The techniques proposed make it possible to reduce the size and/or the performance of the circuits, with a beneficial cost-saving effect on semiconductor materials. Concepts are applied to several technologies, namely CMOS, PCB (Printed Circuit Board) and nanowires.
We present in this book three types of slow-wave structures: (i) coplanar lines (coplanar waveguide or coplanar stripline), which constitute the first type of slow-wave transmission lines genuinely used as such with very good efficiency in CMOS integrated technology, and first implemented by John Long’s team at TU Delft, (ii) microstrip lines, and then (iii) substrate integrated waveguides (SIW). Building upon these three types of lines, we describe a large number of circuits whose performances and dimensions have been enhanced using the slow-wave concept.
Sample topics covered include:
Concepts of energy storage with examples of slow-wave CPW (S-CPW), slow-wave SIW (SW-SIW), and slow-wave microstrip (S-MS),
Transmission line topology and application in integrated technologies (CMOS), including possibilities offered by the BEOL (Back-End-Of-Line),
Effect of the geometrical dimensions on the transmission line parameters (Zc, α, εreff, and Q) and comparisons between conventional CPW and CPS, and slow-wave CPW and CPS,
Performance of slow-wave coupled lines and comparison with conventional microstrip coupled lines.
Slow-wave Microwave and mm-wave Passive Circuits is a highly useful resource for graduate students (best complemented with a basic book on microwaves), engineers, and researchers. The text is also valuable for physicists wishing to implement comparable techniques in optics or mechanics.
