MPI Based Parallel UTD with Analytical Methods to Determine Reflection Points on Cylinders and Cones

We propose an off-axis coupling method for rotating optical signals based on the internal conical reflection. An analytic model of off-axis coupling is developed and verified via simulation and experiment. According to theoretical analysis, the coupling efficiency depends on both the reflectivity of, and the number of reflections between, the conical and the circular plane mirrors. When the reflectivity of the conical and the circular plane mirrors are both constant, i.e. n=0.973, the coupling efficiency is decreased with an increase in number of reflections.Experimental results show good agreement with theoretical predictions. In addition, our experiment demonstrates that the proposed method can achieve a multi-channel signal coupling with a maximum insertion loss of 1.62dB in channel T1 and 0.98dB in channel T2.

“…Many methods have been proposed to calculate the scattering from a cylinder [1][2][3][4][5], but the cylinders in these references are all located in free space. For some objects located over a half-space, such as the ground or sea surface, the influence of the half-space to the scattering mechanism should be considered.…”

Abstract-A method is presented to calculate the monostatic Radar Cross Section (RCS) of an electrically large perfect conducting cylinder vertically located over a dielectric half-space using Physical Optics (PO) technique. The four-path modal method is used to approximate the influence of the half-space to the scattering mechanism. The comparison between the results calculated by this expression and that by Moment Method (MOM) show that the expression is effective and efficient.
