The Multiple Images of the Plasma Lensing FRB
Wang, Yubin
The formation of multiple images can be formed as fast radio bursts (FRBs) pass through the plane of a plasma clump. For analyzing the properties of the multiple images, we adopt the plasma clump with the exponential model and demonstrate that these properties should be observable in some repeating FRBs, such as FRB 121102 and FRB 180916.J0158+65. We argue that analysis of the differences in time delay and in DM between multiple images at different frequencies can serve as a method to reveal the plasma distribution.
