Transmission properties of cantilever probe are discussed in this paper. The transmission efficiency of the cantilever probe is measured. The cu rve of transmission efficiency versus coning angle is given. By the scalar wave equation and Gaussian approximation, transmission properties of this kind of fib er are analyzed and the power losses caused by the binding are also calculated. Fro m the experiments and analysis, it could be come to the conclusion that the bigg er the taper angle, the higher the transmission efficiency.
