Polymer composite materials have been prepared of multiwall carbon nanotubes synthesized by aerosol assisted chemical vapor deposition. To give them anisotropic properties, the obtained films have been subjected to tension. As a result of this deformation, the carbon nanotubes have been preferably oriented in the direction of the tension. The anisotropy of the relative permittivity of the extended films has been measured in the frequency range of 26-37 GHz (Ka band). A model of the correlation between the extent of the response anisotropy and the strain of the composite film has been elaborated. A way to control the electromagnetic response of the material on the basis of the elaborated model has been proposed.
