Abstract [en]

A metamaterial based on carbon nanocoil inclusions is suggested as a means to obtain homogenized magnetism. Demonstrated growth techniques for such nanocoils suggest convenient fabrication is possible. The effective permeability of the medium is studied numerically and shown to exhibit a resonance curve in frequency. By fitting the resonance curve to a Lorentzian-based analytic model and exploring its parameter space, the performance of the nanocoil inclusion configuration is evaluated. These results suggest carbon nanocoils should be effective as magnetic materials in the terahertz frequency regime and possibly beyond. (C) 2015 AIP Publishing LLC.
