Figure 2. Geometrical setting and the theory result.

(a), Illustration of various geometrical quantities used in the analysis: communication radius a, distance b from the middle of the square to the target node, distance b_n from the middle of the square to a neighbor of the target node, the width Δb_n of the bar region, and the cutoff region of the communication circle. (b), Results of Eq. 2 for db = 0.01 and Δb_n = 0.002 (the main features do not depend on the specific values of db and Δb_n).
