Slow-wave Microwave and mm-wave Passive Circuits

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.

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 (Z_c, , _reff, 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.
