The design itself is addressed using an original approach based on first principles: it begins with the design specifications, expresses them in terms of electric and magnetic stresses, establishes appropriate geometry, and arrives at the dimensions. Unconventional topologies are also discussed.403Amazon.comuhttp://www.amazon.com/exec/obidos/ASIN/047189866X/chopaconline-20
