In order to achieve multi-bearing detection

on the basis of understanding the valley-dependent propagation of light in photonic graphene

selecting related parameters of photonic graphene

design reasonable structure model

and simulation calculation is carried out by COMSOL software. The simulation result shows that point source is put in 2D photonic grapheme structure the light beams

from point source transmit along six directions in plane. The sensor using this photonic graphene structure can realize detection in multiply bearing.These research contribute to the development of multi-bearing detection sensor.
