Constitutive relations, dissipation and reciprocity for the Maxwell equations in the time domain

In English

Författare

Summary, in English

The main goal of this paper is to establish general constitutive relations for

the electromagnetic fields E,D,B and H in a time domain setting. The four

basic assumptions of the medium are linearity, invariance to time translations,

causality and continuity. These four assumptions imply that the constitutive

relations are convolutions of Riemann-Stieltjes type. A review of the classifi-

cation of media in bianisotropic, biisotropic, anisotropic and isotropic media,

respectively, is made. Dissipation and reciprocity are defined and the constraints

these concepts make on the constitutive relations are analyzed in

detail. Furthermore, an appropriate form of time reversal and functions of

positive type are introduced and some consequences of these concepts are

showed.
