Optimal Watermark Embedding and Detection Strategies Under Limited Detection Resources 关于数字水印的最新外文资料（2007年）(Optimal Watermark Embedding and Detectio Under n Strategies Limited Resource Detection s digital watermark on the latest information on foreign language (2007))

This MATLAB M-file implements a finite-difference time-domain solution of Maxwell s curl equations over a one-dimensional space lattice comprised of uniform grid cells. To illustrate the algorithm, a 1-GHz sinusoidal wave propagating in a nonpermeable lossy medium (epsr=1.0, sigma=5.0e-3 S/m) is modeled. The simplified finite difference system for nonpermeable.
