摘要
Experimental evidence of left-handed transmission is demonstrated through an array of ferromagnetic microwires. We used amorphous magnetic microwires to take advantage of both electric and magnetic responses locally generating a double negative medium at microwave frequencies, where the ferromagnetic resonance effects take place. The dilution of the responses of the ferromagnetic material provided by the organization of the microstructure in the form of an array provides a means of synthesizing a tailored response to electromagnetic radiation. Finally, transmission characteristics of the analyzed array can be tuned as a function of the applied external magnetic field.
