Differential geometric formulation of Maxwells equations
Maxwell’s equations Maris Ozols January 16, 2012 Abstract Maxwell’s equations in the di erential geometric formulation are as follows: dF = dF = 0 The goal of these notes is to introduce the necessary notation and to derive these equations from the stan-dard di erential formulation Only basic knowledge of linear algebra is assumed 1
Maxwell’s Equations in Terms of Di erential Forms
1 3 Covariant Form of Maxwell’s Equations Maxwell’s equations can be cast into covariant form As Einstein expressed it: \The general laws of nature are to be expressed by equations which holds good for all systems of coordinates, that is are covariant with respect to any substitution whatever (generally covariant)" [BP94]
DIFFERENTIAL FORMS AND THEIR APPLICATION TO MAXWELL’S EQUATIONS
DIFFERENTIAL FORMS AND THEIR APPLICATION TO MAXWELL’S EQUATIONS 3 Lemma 2 3 all forms can be written in what is called an increasing k index ( ifis a k-form)= X I a Idx I where I is an increasing k-index and dx I= dx i 1 ^^ dx i k Lemma 2 4 the wedge product is anti-commutative dx^dy= dy^dx De nition 2 5
Chapter 1 Maxwell’s Equations
To solve Maxwell’s equations (1 15)–(1 18) we need to invoke specific material properties, i e P = f(E) and M = f(B), which are denoted constitutive relations 1 4 Maxwell’s Equations in Differential Form For most of this course it will be more convenient to express Maxwell’s equations in differential form
