Here's a cutting-edge book that focuses on the performance optimization and engineering applications of FDTD simulation systems. Covering the latest developments in this area, this unique resource offer you expert advice on the FDTD method, hardware platforms, and network systems. Moreover the book offers guidance in distinguishing between the many different electromagnetics software packages on the market today. You also find a complete chapter dedicated to large multi-scale problem solving. This practical reference is supported with 250 illustrations, 128 equations, and 11 appendixes filled with helpful data processing techniques related to the FDTD method.$cPublisher abstract. 410 0$aArtech House electromagnetic analysis series. 606 $aFinite differences 606 $aTime-domain analysis 615 0$aFinite differences. 615 0$aTime-domain analysis. 676 $a621.3 700 $aYu$b Wenhua$0739382 701 $aYu$b Wenhua$0739382 801 0$bCaBNVSL 801 1$bCaBNVSL 801 2$bCaBNVSL 906 $aBOOK 912 $a9910816102703321 996 $aAdvanced FDTD methods$94122758 997 $aUNINA
