The final chapter shows how maxwells equations may be combined to produce the wave equation the basis for the electromagnetic theory of light this book is a wonderful resource for undergraduate and graduate courses in electromagnetism and electromagnetics. Preparing maxwells equations for cem simplifying maxwells equations slide 26 0 0 b d hdt e bt d ttet b ttht 1 assume no charges or current sources v 0 0j 0 0 h e hj e e jh 3 substitute constitutive relations into maxwells equations note it is useful to retain uand and not replace. What follows is an appropriate derivation of maxwells equations 4 variants of maxwells equations further we separate different special cases alternatives of maxwells equations system numbered for convenience of presentation variant 1 maxwells equations in the general case in the ghs system are of the form 3 r o t 0. Designed for upper division electromagnetism courses or as a reference for electrical engineers and scientists this book introduces maxwell s equations and electromagnetic waves as soon as possible ie in the first third of the book and then discusses electrostatics magnetostatics induction etc in the light of those equations
