Abstract: A novel physical mechanism for development of Terahertz amplifier with plannar structure is presented in this paper. The theoretical analysis study and numerical calculations have been carried out, the significant results show that 12.69 dB per 1 mm length can be obtained. In principle, the mechanism is quite similar to that of space charge theory.
