Numerical-Based Radar Cross Section Estimation Of Dielectric Cylinder

In this paper two dimensional integral equation based numerical approach is used to analyse the scattered field from a homogenous dielectric circular cylinder. The surface integral equation method replaces the dielectric scatterer surface into equivalent surface electric and magnetic currents. The cylinder contour is discretized into N sections to obtain 2N linear equations, represented in the matrix form. The equation is approximated as a sum of weighted terms using known expansion functions. The resultant matrix equation is solved to obtain electric and magnetic currents and hence cylinder RCS.
