Photonic crystal waveguides with two 60° bends were fabricated in an InGaAsP/InP suspended membrane geometry. The transmission spectrum was measured and the reflectance of the 60° bend was evaluated from Fabry–Perot oscillations using Fourier analysis. It is shown that the reflectance agrees well with the results of a finite element method simulation.

    An in-service pipe always contains elbows and joints at the ends of the pipe. Since the emitted guided waves from a transducer array is bi-directional, any attachments located at both ends of the pipe will cause reflections. For building pipes that are partially covered by wall, the transducer...
