This paper presents a brief detail of the relativistic circle that can be applied for various applications. Relativistic electronics is the challenged device that has the capacity of the new era of technology called civilian technology. Non-relativistic electronics have the limitation that the speed of operation cannot serve the demand of the required applications. The technique to achieve electron transmission faster than light has not been realistic yet. This work has proved that electron speed faster than the speed of light can be realized using the relativistic circle. The functions of the operations are the Rabi oscillation and the successive
filtering. The AC source is input into the microstrip add-drop multiplexer. The wave-particle of the signal oscillation within the microstrip can be obtained. The higher filtering frequency gives the higher electron warp speed. In applications, broadband plasma frequencies can be generated for various applications.
