Abstract
A wireless communication system includes a transmitter configured to transmit at least first and second radio waves having respective different frequencies F1 and F2, an electrically conductive first passive substantially linear medium, an electrically conductive first passive substantially nonlinear medium disposed proximate the first passive substantially linear medium, and a first magnetic film covering at least a portion of the first passive substantially linear medium. When the transmitter transmits the first and second radio waves, the first passive substantially linear and nonlinear media receive the first and second radio waves and generate first and second signals propagating therein at the respective frequencies F1 and F2. At least one intermodulation signal having a frequency F3 equal to nF1+mF2, where m and n positive or negative integers, is generated in the first passive substantially nonlinear medium. The first magnetic film reduces the at least one intermodulation signal by at least 2 dB.
