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. 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. Recall that f is the density of free charges jf is the free current density due to the motion of the free charges p is the electric dipole moment density and m is the magnetic dipole density it is presumed that the total charge density t and the total current density jt are prescribed functions of position and of time. Free downloada new solution of maxwell equations for a vacuum for wire with constant and alternating current for the capacitor for the sphere etc is presented first it must be noted that the proof of the solutions uniqueness is based on the law of energy conservation which is not observed for instantaneous values in the known solution the solution offered o complies with the . 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
