Title: An inverse problem for Maxwell's equations with Lipschitz parameters,
Abstract: We consider an inverse boundary value problem for Maxwell's equations, which
aims to recover the electromagnetic material properties of a body from
measurements on the boundary. We show that a Lipschitz continuous conductivity,
electric permittivity, and magnetic permeability are uniquely determined by
knowledge of all tangential electric and magnetic fields on the boundary of the
body at a fixed frequency.
