A spin interferometer utilizing the Rashba effect is proposed. The novel design is composed of a 1-D straight wire and a 1-D half-ring. By calculating the norm of the superposed wave function, we derive analytical expressions to describe the spin interference spectrum as a function of the Rashba coupling strength. Presented spin interference results are identified to include i) the quantum-mechanical 4π rotation effect, ii) the geometric effect, and iii) the Shubnikov-de Haas-like beating effect.
