Abstract

We present experimental results of electromagnetic wave modulation by the application of AC currents along a ferromagnetic microwire at the frequency range where left-handed transmission is observed. It is demonstrated that transmitted microwave signals through a waveguide mount are modulated by the current applied to the wire. From the measurements, we have extracted information about the magnetic susceptibility behavior of the microwires. © 2012 American Institute of Physics.
