Abstract. The possibility of application resistive net method for analysis of local conductivity anisotropy of graphene containing shungite is investigated. It is brought the importance of task establishment for creation of microwave radiation screen. With application of electric-forced microscopy method it is received the cards of carbon and quarts distribution in specimens with small, middle and large carbon containing. It is made the binary discretization of received cards. On the basis of discretized cards it is made the construction of resistive nets. It is found the resistance cards dependences of the resistance quarts cell nominal. It is found two varieties of this dependencies: increment with saturation and increment with linearity. It is shown that the increment with saturation is dependent from through channel and increment with linearity is dependent from its absence. For revealing of anisotropy it is investigated the card resistance in two orientations: in initial and in turned on angle of 90 degree. It is proposed the anisotropy parameter which is equal to ratio of difference between cards resistances before the turning and after its to sum of these resistances before and after turning. It is found that for specimens with small and large carbon containing the anisotropy parameter is equal about 0.06-0.07 norm. un. and for specimens with middle carbon containing the anisotropy parameter is more increased and equal to 0.24 norm. un. It is proposed some recommendations for further development of investigations.

Keywords: graphene containing shungite, electric-forced microscopy, resistive net, anisotropy.
