Errata

Most of these errors have been corrected in the 2012 Dover edition, and in the electronic (PDF) version of the Solutions Manual.

[p. 15: In Eq. (1.35), the lightface P should be in boldface.]

[p. 27: In Eq. (1.70), the lightface M should be in boldface.]

[p. 49: In the first printing, the p in Eq.(2.22) should be full size. The q should be light-face (thanks to Sergio Marra).]

[p. 52: The Q and q should be light-face (thanks to Sergio Marra).]

p. 57: The label of Fig.2-8's frame (a) should be "Monopole', not "Dipole". [Thanks to Michael Schutten.]

p. 60: The final piece of Eq. 2.54 is missing a negative sign [Thanks to Junping Shao.]

p. 63: Eq.2.69: the absolute quantity in the denominator of the integrand should be squared. [Thanks to Ammar Durghalli.]

[pp. 63-64: Don't confuse the asterisk used for the footnotes with the symbol for magnetic charge (thanks to Sergio Marra).]

[p. 85: In Eqs. (3.25) and (3.26) and the text line between, the symbol theta should be in italic-style type.]

p. 99: In the second formula of Eq. 3.60, the subscript should be the numeral one, not the letter el [Thanks to Junping Shao.]

p. 116: The section number for "Poisson's Equation" should be 3.7.

p. 137: Eq.4.33: the sign of the E-derivative term should be positive, not negative. [Thanks to Chris Wallace.]

p. 141, lines 4 and 6: Change "vector" to "vector field" (3 places). Dagger footnote: It appears that the commonly named "[H.A.] Lorentz" gauge was actually introduced by [L.] Lorenz in 1867. See Rohrlich, Am. J. Phys. 70, 411 (2002).

[p. 145: In the first printing, in Eq.(4.73) the F in the middle expression was not printed cleanly.]

p. 148: In the first printing, in the unnumbered display equation at top of the page, change the E to D.

p. 196: In the first printing, in Prob. 5-2, the final term of the first display equation should have a c-squared in the denominator. (There are corresponding errors in the Solutions Manual, p. 67--see below.)

p. 213: In the first printing, there is a substantial error in the argument involving Eqs. (6.54-55). The wavevector k in Eq.(6.54) is complex, and no longer perpendicular to E2. To work out the algebra requires distinguishing between the polarization component E-perp of Eq.(6.27) and the component E-par of Eq.(6.33), in the second medium. The result is that the term |E2|^2 in Eq.(6.55) is replaced by (|E-par|^2 - |E-perp|^2). The expression remains pure-imaginary, and thus the normal component of the Poynting vector does indeed vanish for any superposition of the two polarizations. More interesting results concern the (nonzero) Poynting component tangential to the interface, addressed in Prob. 6-12, which is incorrectly worked out in the Solutions Manual, p.79--see below.

[p. 219: The running section header should be 6.5, not 5.6 (thanks to Lance Labun.]

p. 220: In the first line of Eq.(6.74), there should be a negative sign immediately following the opening square bracket. Likewise, a negative sign should be inserted in front of the first term of Eq.(6.76). [Thanks to Christian Morath.]

p. 242: Insert a negative sign following the first equals in Eq.(7.75). [Thanks to Lance Labun.]

p. 260: In the first printing, Eq. (8.22) is missing a factor of 1/c on the right-hand side.

pp. 271-2: In Fig. 8-2 and Eq.(8.76), the angle theta should have a subscript p. In Eq.(8.72), the subscript on the first term on right side should be r, not i. [Thanks to Evangelos Manesis.]

p. 286: In Fig. 8-7, the tail of the theta arc-arrow should extend to the extension of the line QP. That is, the angle is between the acceleration's direction QP and the observation direction PR. [Thanks to Robert Caldwell.]

p. 306: In Eq.(9.64), insert a negative sign and the coefficient k in the exponent inside the integral. [Thanks to Jerome Fung and Melisa Sologuren.]

p. 337: In Eq.(10.11), the upper limit on the integral should be pi, not 2*pi. [Thanks to Jerry Eriksson.]

[p. 363: In Eq.(10.82), the first omega on the right-hand side should be in boldface.] [Thanks to Per Eric Lindgren.]

pp. 444-5: The function sinu/u in Eq. (12.39), identified as the sinc function in the following text, is also the zero-order spherical Bessel function, j^0(u).

[p. 453: The halftone of the Airy pattern is printed at too high contrast; the second and higher-order "bright" rings have been lost.]

p. 481: In the first printing, in the 2nd line before "Normal Modes" subhead, insert to read "... no qualitative difference in beamshape between ...".

p. 489: The third piece of Eq. 14.5a, directly equating the x3 partials, is wrong; the relation requires an expansion analogous to Eq. 14.5b, which adds two more terms to Eq. 14.6. [Thanks to Simon Ellingsen.]

[p. 499: In the first printing, in Eq. (14.46), the U should be in the same 4-vector font as in Eq. (14.35).]

[p. 507: In Eq. (14.67), the boldface G should be in lightface italic.] [Thanks to Matthew Stone.]

p. 509: In Eq. (14.75), in the final matrix's 4th row, 2nd column, the subscript on E-prime should be 2, not 3. [Thanks to Matthew Stone.]

p. 511: In the 4th-from-last display line (between "Hence" and "Therefore"), delete the spurious plus sign preceding the equals. [Thanks to Matthew Stone.]

Solutions Manual

Most of the following pertain to hardcopy printings of the Solutions Manual, and have been corrected in the electronic edition now available.

p. 57: In Prob. 4-9, the final formula quoted for alpha can be simplified slightly using the fact that alpha(A) + alpha(1/A) = 1.

p. 58: In Prob. 4-11, in the first line of the algebra, delete the exponent 1/2 on the denominator sum-of-squares. [Thanks to Hiro Miyake.]

p. 67: In Prob. 5-2, the coefficient of the final term of Eq.(1) should be c-squared in the denominator. The same correction is needed in the dJ/dt term in the integral formula for E near the end of the Solution.

p. 79: For Prob. 6-12, see errata for p. 213 of the text. The complex-conjugate wavevector k2* has a real x-component and a negative imaginary z-component. Similarly,
E2 = ( iQ E-par , E-perp exp(i delta) , W E-par ),
where delta is the phase of the perpendicular component relative to the parallel component of E2. Expansion of <S2> as given in Eq. (6.54) yields
Re<S2>x ~ -W (E-par^2 + E-perp^2)
Re<S2>y ~ 2 Q W E-par E-perp sin(delta)
The x-shift, in the plane of incidence, is associated with the Goos-Haenchen effect; the y-shift, transverse to the plane, washes out for unpolarized light (random delta).

p. 101: In Prob. 9-16, in the middle term of Eq.1, delete the 1/2 factor. Or alternatively omit the averaging brackets and add the subscript (zero) to the current I.
