namely, the method of moment (MoM), the finite element method (FEM), and the finite-difference time-domain (FDTD) method. Numerous monographs can be found addressing one of the above three methods. However, few give a broad general overview of essentials embodied in these methods, or were published too early to include recent advances. Furthermore, many existing monographs only present the final numerical results without specifying practical issues, such as how to convert discretized formulations into computer programs, and the numerical characteristics of the computer programs. In this book, the authors elaborate the above three methods in CEM using practical case studies, explaining their own research experiences along with a review of current literature. A full analysis is provided for typical cases, including characteristics of numerical methods, helping beginners to develop a quick and deep understanding of the essentials of CEM. . Outlines practical issues, such as how to convert discretized formulations into computer programs. Gives typical computer programs and their numerical characteristics along with line by line explanations of programs. Uses practical examples from the authors' own work as well as in the current literature. Includes exercise problems to give readers a better understanding of the material. Introduces the available commercial software and their limitationsThis book is intended for graduate-level students in antennas and propagation, microwaves, microelectronics, and electromagnetics. This text can also be used by researchers in electrical and electronic engineering, and software developers interested in writing their own code or understanding the detailed workings of code.Companion website for the book: www.wiley.com/go/sheng/cem. 606 $aElectromagnetism$xData processing 606 $aElectromagnetism$xMathematical models 615 0$aElectromagnetism$xData processing. 615 0$aElectromagnetism$xMathematical models. 676 $a537.0285 700 $aSheng$b Xin-Qing$f1968-$0845588 701 $aSong$b Wei$0845589 801 0$bCaBNVSL 801 1$bCaBNVSL 801 2$bCaBNVSL 906 $aBOOK 912 $a9910208840203321 996 $aEssentials of computational electromagnetics$91887762 997 $aUNINA LEADER 01251nam0 22002771i 450 001 UON00325996 005 20231205104200.481 100 $a20090709d1959 |0itac50 ba 101 $aeng 102 $aGB 105 $a|||| ||||| 200 1 $aAmerican Critical Essays$fHarold Beaver 210 $aLondon$cOxford University Press$d1959 215 $aXVI, 364 p.$d23 cm. 606 $aLetteratura americana$xStudi$3UONC065581$2FI 620 $aGB$dLondon$3UONL003044 676 $a810$cLetteratura americana in inglese$v21 700 1$aBEAVER$bHarold$3UONV185790$0700052 712 $aOxford University Press$3UONV245947$4650 801 $aIT$bSOL$c20250530$gRICA 912 $aUON00325996 950 $aSIBA - SISTEMA BIBLIOTECARIO DI ATENEO$dSI Angl SERPIERI 064 $eSI 41002 5 064 950 $aSIBA - SISTEMA BIBLIOTECARIO DI ATENEO$dSI VII A BEA $eSI LO 65748 7 950 $aSIBA - SISTEMA BIBLIOTECARIO DI ATENEO$dSI VII A BEA bis $eSI LO 1120 7 996 $aAmerican Critical Essays$91369158 997 $aUNIOR LEADER 04602nam 22005895 450 001 9910768481603321 005 20250807132444.0 010 $a9783031399008$b(electronic bk.) 010 $z9783031398995 024 7 $a10.1007/978-3-031-39900-8 035 $a(MiAaPQ)EBC31016772 035 $a(Au-PeEL)EBL31016772 035 $a(OCoLC)1415633494 035 $a(CKB)29374712100041 035 $a(DE-He213)978-3-031-39900-8 035 $a(oapen)doab132005 035 $a(EXLCZ)9929374712100041 100 $a20231211d2024 u| 0 101 0 $aeng 135 $aurcnu|||||||| 181 $ctxt$2rdacontent 182 $cc$2rdamedia 183 $acr$2rdacarrier 200 10$aCultural Change in Post-Migrant Societies $eRe-Imagining Communities Through Arts and Cultural Activities /$fedited by Wiebke Sievers 205 $a1st ed. 2024. 210 1$aCham :$cSpringer International Publishing :$cImprint: Springer,$d2024. 215 $a1 online resource; xix (268 pages)$cblack/color illustrations 225 1 $aIMISCOE Research Series,$x2364-4095 311 08$aPrint version: Sievers, Wiebke Cultural Change in Post-Migrant Societies Cham : Springer International Publishing AG,c2024 9783031398995 327 $aPart I: How to conceive change: Theoretical and methodological considerations -- Chapter 1.

It proposes theoretical and methodological approaches that highlight how ideas of change expressed in artistic and cultural practices spread and lead to wider cultural change. The book also looks at the slow processes of change in large cultural institutions that emerged at a time when culture was nationalised. It explains how individual and group activities can have an impact beyond their immediate surroundings. Finally, the book discusses how migration researchers have cooperated with arts and cultural producers and used artistic means to increase the effect of their research in the wider public. As such, the book provides a great resource for graduate students and researchers in the social sciences and the humanities who have an interest in migration studies and want to move beyond interpreting the world towards changing it. 410 0$aIMISCOE Research Series,$x2364-4095 606 $aEmigration and immigration 606 $aCulture$xStudy and teaching 606 $aEmigration and immigration$xSocial aspects 606 $aHuman Migration 606 $aCultural Studies 606 $aSociology of Migration 615 0$aEmigration and immigration. 615 0$aCulture$xStudy and teaching. 615 0$aEmigration and immigration$xSocial aspects. 615 14$aHuman Migration. 615 24$aCultural Studies. 615 24$aSociology of Migration. 676 $a304.8 700 $aSievers$b Wiebke$0802763 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 912 $a9910768481603321 996 $aCultural Change in Post-Migrant Societies$93658468 997 $aUNINA
