Abstract
Canadian ships must be protected from weapons that can damage or destroy the vessel. Ships are identified and targeted according to their signatures. One of these signatures, the radar cross section, may be reduced through the use of radar absorbing materials. Ideal radar absorbing materials have equal permittivity and permeability. Unfortunately, although there are materials available having permittivity fw materials having permeability are available. But two novel material types could be investigated for EM signature control. The first type, molecular magnets, is polymer-like materials being developed currently for their data storage capabilities. The second type is materials having negative permeability and/or negative permittivity. These materials are left-handed and have unique properties. An investigation of these materials will be undertaken in the search for EM signature control materials. Of further consideration are the potential advantages these novel radar absorbing materials might have over current technology.
