N2 - We study synchrotron maser emission and associated particle acceleration at electron-ion relativistic shocks by PIC simulations. Relativistic shocks emit intense electromagnetic waves from the shock front via the synchrotron maser instability. This synchrotron maser emission induces electrostatic plasma waves (i.e., wakefield) and transverse filamentary structures in the upstream region via the stimulated/induced Raman scattering and filamentation instability, respectively. Some lucky particles in the phase of the deceleration by the wakefield enter the filamentary structures. Then they are reflected by the wakefield and decoupled from the upstream bulk flow. These decoupled particles can feel the motional electric field and efficiently accelerated.
