We find that both radiation mechanisms work for a neutron star (NS) central engine with $B\\gtrsim 10^{12}$ G, while for the synchrotron maser, the central engine can also be an accreting black hole (BH) with $B\\gtrsim 10^{12}$ G and a white dwarf (WD) with $B\\sim 10^8-10^9$ G. We study the electromagnetic counterparts associated with such central engines, i.e., nebulae for repeating FRBs and afterglows for non-repeating FRBs.
