formulas of wave propagation in a dielectric slab

http://faculty.kfupm.edu.sa/EE/ajmal...esis_Chap2.pdf

thanks all
but i have a problem yet
could any one please tell me the below codes of wave propagation refer to wich formula?
CNA = 1.0 - SIG*DT/(2.*E0*ER)
CD = 1.0 + SIG*DT/(2.*E0*ER)
CA = CNA/CD
CNB = DT/(E0*ER*DZ)
CB = CNB/CD;
Ex(1,I) = CA*Ex(1,I) - CB*(Hy(1,I+1) - Hy(1,I))
thanks

Riiighhht...tell ya what...why dont you stop acquiring "formulas" and try deriving some of these for yourself! If not interested in deriving...then study the book more and memorize the formulas...

As an aside, formulas tend to get you nowhere if you do not know the fundamental physics.

thanks ckshivaram & MRAMA

Looks like FDTD formulation from central difference. Try to read Taflove & Hagness book or Sulluvian
