In this work, an FBG-based OFA was produced, which, together with two FBG sensor arrays, was used to analyze the impact of induced corrosion on the pipeline natural frequency (fn_pipeline) when this structure was buried in sand. Each FBG sensor array constituted five gratings multiplexed into...
ReflectanceIn this research, fiber based BiFeO3-air structure is lucidly investigated at wavelength of 1.55渭m for optimization of reflectance, diffraction and dispersion loss in order to maximize the transmitted efficiency. Here bismuth ferrite (BiFeO3) is taken as odd layer and air is taken as ...
