On the electromagnetic instantaneous response

Research output: Book/ReportReport

Abstract

The instantaneous response models the rapid part of the interaction between
electromagnetic fields and materials. From a physical point of view the instantaneous
response is non-observable and from a mathematical point of view
it constitutes the principal part of the Maxwell equations. In this paper, it
is shown that the instantaneous response is not uniquely determined from a
given set of values of the constitutive map. The given values only give an
upper bound on the size of the instantaneous response. A numerical example
illustrates the non-uniqueness of the instantaneous response.
