講演題目: Absorption of the microwave and THz radiation in ultrathin carbon films

Abstract  PDFファイル

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.
