講演題目: Absorption of the microwave and THz radiation in ultrathin carbon films
Abstract
Experimental results on the intraband absorption in graphene and nanometricaly thin
pyrolytic carbon films are presented. It is shown that films with thickness much less
than skin depth are capable to absorb up to 50% of the incident radiation. This opens
avenues towards development of novel ultralight coatings with enhanced shielding
efficiency in the microwave spectral range. The properties of the graphene/dielectric
sandwich like structures in the THz range are discussed. The
transmission/reflection/absorption of these structures in the THz range can be
changed by varying chemical potential of the graphene, while absorbance can be also
tuned by changing the thickness dielectric substrate.
