Errata as of 17 July 2007 (note that some of these errata may have been corrected in the 2nd printing)

p. 26, line 8, "devolopment", should read "development".

p.57 Eq. (2.92) "X(t)" should be "x(t)".

p.72. 3rd line of eq. (3.15): second term  "-E_x(...)" should  read "-E_y(�)".

p.75. 3rd line of eq (3.22), "E_x^{tot}(i+1/2,j,n)" should read "E_x^{tot}(i_L+1/2,j,n)" (i.e., subscript L missing in i).

p.95. In both equations at the end of the page, all the terms "\Gamma*e^{j 2 \beta_1x}" should read "\Gamma*e^{j 2 \beta_1x x}", ie. there is a terminal x missing in the argument of the exponent.

p.96. Just before the eq. (3.44), in the expression for "\eta_2", in the denominator of the fraction under the square root, "\sigma/(j \omega \mu_2)" should read "\sigma/(j \omega \epsilon_2)"

p.98. in all three equations (3.51 to 3.54), the last factor "\beta_2y y" should be part of the exponent.

p.242 line 13 and 14 of text: j is missing from in front of the tan \delta term on both lines. 

p.302 Eq. (9.38). This equation is correct, but note that it assumes a homogeneous domain, with 
\epsilon constant throughout. 

p.318. For consistency with the rest of the book's notation, [e], [e_f], [e_p] etc on this page should read {e}, {e_f}, {e_p} etc.

p.328 Fig 9.7 The mesh size h in this figure is in centimeters.

p.360. Eq. 10.25, first line. The bold n should be \hat{n} (ie caret-ed, not bold) for consistency with the rest of the book's notation. Also on p.360, the bold K in K^{int} in the first line of 10.26 should be typeset as \vec{K}^{int} (which puts an arrow over K); similarly, J^{int} K^{int} on the last line of the 2nd para on this page, and H on the 2nd line of the 3rd para. Again, these are not actually wrong, but are inconsistent with the notation in the rest of the book. 

p.369 Eq. (10.45) 3rd line, the term "(1-2\beta[S])" should read "(1-2\beta)[S]"
 
p.374. Eq. (10.52), the last entry should be 12, not 11.

p.391. line above eq. (A.5): "A= (1/2 \ell h) = (1/2 \ell_3 \ell_2 \sin \theta_1)" should read "A= (1/2) \ell h = (1/2) \ell_3 \ell_2 \sin \theta_1", (i.e. closing parentheses should be moved, twice).
