Book Dec 1992Latest edition at the time was that Mr. Fluke had written a very good and useful volume, its only flaw being that it focused on just half of the EMI emissions problem. This, of course, was also its strength; although radiated and conducted emissions do not exist in separate worlds, it can be useful, at least as a

Frank Achtenhagen,Michael Bendorfllions of input/output circuits, printed traces, flat cables and so forth, is impossible to mathematically model with accuracy—at least within a reasonable computing time, by today’s state of the art. The exact calculation of the E and H fields radiated by a simple parallel pair excited by a pulse train is already a complex mathematical process.

The method described in this chapter allows the designer to identify and reduce out-of-spec radiations without necessarily having to return to an RFI test site for each trial fix.

Controlling Radiated Fields from Switch-Mode Power Supplies,ern, primarily because of its conducted emissions but, to a lesser extent, its radiated emissions. The first aspect is covered extensively in Ref. 10, by J. Fluke, a book which is more or less a parent of the present one. Therefore, we will concentrate on radiated field generation and suppression.
