The Effect of a Reflecting Cylinder in Two-Dimensional Inverse Source Problem for Circumference Geometries

The inverse source problem with a perfect electric conducting (PEC) reflecting cylinder in two-dimensional plane is discussed in this paper. The reflecting cylinder is placed coaxially with the observation domain. The induction currents on the reflecting cylinder are analyzed by applying the boundary condition. A new operator is defined for calculating the electric field of observation domain. The rebuilding currents are then computed using the singular value decomposition (SVD) of this new operator. The numerical experiments verify that the reflecting cylinder enhances the accuracy in rebuilding currents.
