Abstract

A wireless communication system including an electrically conductive passive medium capable of simultaneously propagating therealong electromagnetic first and second currents at different respective frequencies F1 and F2, the electrically conductive passive medium including an electrically conductive first passive linear medium portion adjacent an electrically conductive first passive nonlinear medium portion, the first passive nonlinear medium portion capable of generating an intermodulation current based on a nonlinear interaction between the first and second currents, the intermodulation current having a frequency Fi equal to nF1+mF2 and propagating along the first passive nonlinear medium portion, m and n being positive or negative integers; and a first magnetic film disposed proximate an electrically conductive external surface of the first linear medium portion, such that when the first and second currents propagate along the first passive linear medium portion toward the first passive nonlinear medium portion, the magnetic film reduces or prevents the generation of the intermodulation current in the first passive nonlinear medium portion by attenuating at least portions of the first and second currents.
