Terahertz Magnetic Response from Artificial Materials

T. J. Yen,1* W. J. Padilla,2* N. Fang,1* D. C. Vier,2 D. R. Smith,2 J. B. Pendry,3 D. N. Basov,2 X. Zhang1{dagger}

We show that magnetic response at terahertz frequencies can be achieved in a planar structure composed of nonmagnetic conductive resonant elements. The effect is realized over a large bandwidth and can be tuned throughout the terahertz frequency regime by scaling the dimensions of the structure. We suggest that artificial magnetic structures, or hybrid structures that combine natural and artificial magnetic materials, can play a key role in terahertz devices.
