title: Wound diagnostics with microwaves.
abstract: The reflection of electromagnetic waves on material surfaces is very depending on the electric and magnetic properties of these materials, on their structure and on the surface texture. Therefore the different layers and dielectric properties of healthy and unsound body tissue also show different reflection behavior towards incidentating electromagnetic waves. By analyzing the reflected signals of incident electromagnetic waves, it is possible to get information about the inner structure of the reflecting body tissue. This effect could then be used for a contactless analysis of body tissue e.g. to gain crucial medical information about healing processes. In this paper the results of several full wave simulations of various tissue structures are presented and the significance and usability of this method is shown.
