Abstract

The present report gives an introduction to mathematical modelling of signature materials by the application of mixing-formulas. The report is focused on methods to compute the effective dielectric properties of materials mixtures. Examples are given how these computational models can be used for the analysis and design of radar absorbing materials and structures. Some problems to be addressed by further research in mathematical modelling of signature materials are also identified. The report is a compilation of methods described in literature, as well as experience gained at a research visit to the Electromagnetics Laboratory, Helsinki University of Technology March 14-15, 2002.
