This unique “how to“ book is an ideal introduction to
electromagnetic field-solvers. It provides you with helpful advice on selecting
the right tools for your RF and high-speed digital circuit design work. The
focus is on the strengths and weaknesses of the major commercial software
packages. . Featuring full-color illustrations, this practical resource offers you invaluable tips and techniques on the use and evaluation of these products.
A
generous amount of case study material is presented, including a ‘what went
wrong in the design process’ discussion, when applicable. Color plots of
current density and various field quantities included throughout the book help
you better understand the fundamental behavior of the circuits being studied.
Stress is given to the impact of meshing, geometrical resolution and
convergence on the solution process, showing you that you can better control
and greatly influence the quality and speed of the solution. You’ll appreciate
solving problems using the fundamental, underlying physics, rather than the
more approximate methods used in the past. Specific design information on
transitions in multilayer PCBs and PCB connectors is not available in any other
book.
