Best practice in circuit board design

Best practice in circuit board design, by Tim Jarvis B-KTL, Hull UK

This paper introduces the basic principals of EM wave propagation within printed circuit board (PCB) structures.
All best practice rules and methods are based on the physics of EM waves. To select the appropriate method and apply it correctly requires a first principles understanding of EM propagation
