In this paper the one-dimensional numerical results of the simulation on the reflection of electromagnetic fields from perfect conductor traveling at extremely high velocity were presented. Maxwell’s equations were numerically solved through the application of the method of characteristics (MOC) where the perfect conductor was set to travel as fast as 90 percent of the light speed either approaching or receding from the incident electromagnetic fields. In order to accurately predict the behavior of electromagnetic fields interacting with moving object, the relativistic boundary conditions were used in MOC in conjunction with the characteristic variable boundary conditions. Both time- and frequency-domain results were demonstrated. The validation of the numerical accuracy is carried out by comparing the computational results with the theoretical Doppler values.
