This method, popular in science and engineering, essentially reduces PDEs to a set of ordinary differential equations that can be integrated using standard numerical integration methods. Its significant advantage is that the analysis algorithms follow the physical wave propagation and are therefore efficient. This is because the fields on the discretisation lines are described by generalised transmission line (GTL) equations. 410 0$aRSP 606 $aElectromagnetic devices$xMathematical models 606 $aElectromagnetism$xMathematics 606 $aDifferential equations, Partial$xNumerical solutions 615 0$aElectromagnetic devices$xMathematical models. 615 0$aElectromagnetism$xMathematics. 615 0$aDifferential equations, Partial$xNumerical solutions. 676 $a530.14/1 676 $a530.141 700 $aPregla$b Reinhold$0949547 701 $aHelfert$b Stefan$0949548 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a996212468103316 996 $aAnalysis of electromagnetic fields and waves$92146247 997 $aUNISA
