In this study, the plasma-photonic-crystal-like beam–plasma system has been proposed. Two types of plasma-photonic-crystal-like beam–plasma systems, namely plasma-vacuum-plasma-vacuum-plasma (PVPVP) beam–plasma system and plasma-vacuum-plasma (PVP) beam–plasma system, have been simulated using the particle-in-cell method. The simulation results show that the beam electrons can be focused without an external magnetic field, and the electromagnetic (EM) radiation can be observed. For the PVPVP beam–plasma system, the EM radiation frequency is 0.9035 THz, and the electron efficiency that the beam electrons give out their energy to the EM wave is 3.06%. For the PVP beam–plasma system, the EM radiation frequency is also 0.9035 THz, but the electron efficiency can be up to 10.5%. This work can contribute to the engineering practice of the beam–plasma system.
