Backscattering From Two Identical Cylinders Illuminated by an Obliquely Incident Plane-Wave


  • Juang-Lu Lin


A study is presented of the backscattering from two identical, perfectly conducting, thin cylinders illuminated by a plane wave at an arbitrary angle of incidence. The theory is based on an integral equation method. By decomposing the induced currents into symmetric and antisymmetric modes, the simultaneous integral equations for the induced currents are converted into independent integral equations similar to the one for a single cylinder for which the solution has already been carried out. The induced current on the cylinders and the backscattering cross sections of the cylinders are determined. Comparisons are made between the calculated and the measured values of the echo area. The experimental results are in good agreement with theory.
