In this ®gure, since we are testing the numerical accuracy of the computation formulae, we let PBOX POUT PDE PDM j ÀPWE PWM and compare PIN and PBOX . As can be seen from Fig. 14, the real and imaginary parts of PIN (cross) and PBOX Copyright © 2000 Marcel Dekker, Inc. 52 Chapter 2 Figure 14 Plots of the real and imaginary parts of the complex Poynting theorem terms as results from Eqs. 21±27 given the same Poynting box as was used in Figs. 12 and 13 are shown. (solid line) are numerically indistinguishable from one another, showing that the numerical computations have been carried out accurately.
We may demonstrate that Vn eqn y is a solution of Eq. 8 by direct substitution. We have for n 1; 2, d=dy Vn eqn y Vn d=dyeqn y qn Vn eqn y . But qn Vn AVn , hence d V eqn y A Vn eqn y dy n 2:2:9 which is the original equation. Superposition of the distinct modes of Vn eqn y then gives the full EM solution.
