Microsized carbon fibres exhibit strong resonant absorption at terahertz frequencies. Using near-field terahertz time-domain spectroscopy, we probe their conductivity by analysing the degree of field enhancement produced by plasmonic resonances. We demonstrate, theoretically and experimentally, the potential usability of carbon microfibres as terahertz absorbers with engineerable response.
