Chapter 1 Maxwell’s Equations
Using these theorems we can turn Maxwell’s integral equations (1 15)–(1 18) into differential form Differential Form of Maxwell’s Equations Applying Gauss’ theorem to the left hand side of Eq (1 15) replaces the surface integral over ∂V by a volume integral over V The same volume integration is
4-2 Maxwell’s Equations for Electrostatics
10/10/2005 The Integral Form of Electrostatics 1/3 Jim Stiles The Univ of Kansas Dept of EECS The Integral Form of Electrostatics We know from the static form of Maxwell’s equations that the vector field ∇xrE() is zero at every point r in space (i e , ∇xrE()=0) Therefore, any surface integral involving the vector

4 1 Maxwell’s Equations The next simplest form of the constitutive relations is for simple homogeneous isotropic dielectric and for magnetic materials: D =E B =μH (1 3 4) These are typically valid at low frequencies The permittivity and permeability μ are related to the electric and magnetic susceptibilities of the material as follows
