For propagation antiparallel to the magnetic field B0, the signs are reversed. This
is the extension of (7.59) to include a static magnetic induction. It is not
completely general, since it applies only to waves propagating along the static
field direction. But even in this simple example we see the essential characteristic
that waves of right-handed and left-handed circular polarizations propagate
differently. The ionosphere is birefringent. For propagation in directions other
than parallel to the ...
(b) Use the WKB approximation to treat the propagation of waves directed
vertically into the ionosphere (k = 0), assuming that the dielectric constant is
given by (7.59) with a plasma frequency co,(z) governed by an electron density
like that shown in Fig. 7.11. Verify that the qualitative arguments in Section 7.6
hold, with departures in detail only for iD~o)rJm. (c) Using the WKB results of (b)
and the concepts of the propagation of a pulse from Section 7.8, define an
effective height of the ...
propagate; the rest are cutoff or evanescent modes. Far away from any source,
obstacle or aperture in the guide the fields are relatively simple, with only the
propagating modes (often just one) present with appreciable amplitude. Near a
source or obstacle, however, many modes, both propagating and evanescent,
must be superposed in order to describe the fields correctly. The cutoff modes
have sizable amplitudes only in the neighborhood of the source or obstacle; their

A soul crushing technical manual written by a sadist that has served as the right of passage for physics PhDs since the dawn of time. Every single one of my professors studied this book, and every ... Read full review
Text is quite readable and appropriate for a first-year graduate text in physics. A "bible" I return to again and again.
Thinking back, I recall struggling over some sections for which I was not adequately prepared, including time-dependent EM fields. That aside, this was the text for my most favorite class in grad school.
If you are a fan of transformational solutions to differential equations then this is the text for you. Here is where I really learned about Fourier and other special function transformations as well as solving diffeq problems in special coordinate systems. I did very well in quantum mechanics thanks to this text.
I fear that students today may not have the same preparation that was common 30 years ago. Back then, expectations were different. In particular, this text is hardly aware of computational problem solving. It is focused on analytics.
