Summary:
A quantum system with a stub-structured potential is considered to be usable as a frequency discriminator of terahertz wave receiver system. In this quantum system, the electron wave is reflected or transmitted near the connection area of the stub depending on the momentum of the electron wave. In this study, by numerical analysis of the propagation of the electron wave using the difference method, we analyzed the change of reflection and transmission characteristics with respect to the momentum of the electron wave. In addition, we calculated the sample trajectories of electrons by stochastic quantization on which circuit simulator model of terahertz wave receiver system is based. By the analysis, we have confirmed that the quantum system with a stub-structured potential functions as a frequency discriminator.
