Abstract: A material contains a curable liquid polymer containing suspended nanoparticles capable of exhibiting a magnetic property. The nanoparticles are present in a concentration sufficient to cause the curable liquid polymer to flow in response to application of a magnetic field, enabling the material to be guided into narrow regions to completely fill such regions prior to the polymer being cured. A method includes applying a filler material to at least one component, the filler material including a heat curable polymer containing nanoparticles, and applying an electromagnetic field to at least part of the filler material. The nanoparticles contain a core capable of experiencing localized heating sufficient to at least partially cure surrounding polymer. Also disclosed is an assembly for use at radio frequencies. The assembly includes a substrate and at least one component supported by the substrate. The substrate contains a thermoplastic or thermoset polymer with suspended nanoparticles capable of exhibiting a magnetic property. The nanoparticles are of a type and have a concentration in the polymer selected to provide a certain dielectric permittivity, magnetic permeability and dissipation factor.
