Detection of high energetic alpha particle radiation through metal clad planar waveguide based sensor

In present communication, the dispersion characteristic, electromagnetic field distribution and performance parameter of a metal clad planer waveguide sensor for detection of high energetic alpha particle radiation is simulate and studied. Using the boundary matching technique, the modal equation and other necessary formulae of proposed waveguide are derived. It is observed that the dispersion characteristics of waveguide have their usual shape in presence of alpha particle radiation. The cutoff film thickness of waveguide decreases with increase of the dose of alpha particle radiation. The TE mode analysis of proposed waveguide based sensor shows the sensitivity, detection accuracy and overall performance are 153.33°/RIU, 5.75 and 1916.67 RIU−1, respectively. Our analysis also shows that the obtained detection accuracy and overall performance of proposed waveguide for TE mode analysis are sufficiently large comparison to the TM mode analysis.
