Theoretical and experimental study of electromagnetic scattering from coated cylinders

Theoretical and experimental studies carried out for finite coated cylinders are presented. The numerical method that is used is based on the moment method developed by Mautz and Harrington (1979), which is applicable to bodies of revolution (BORs). The BOR can be defined as a body whose surface is generated by rotating a planar curve about the axis of symmetry. It is applied to finite cylinders with perfectly conducting, dielectric, and coated material compositions. In order to evaluate the accuracy of the formulation and the code, laboratory measurements have been carried out covering frequencies from resonance to the lower end of the high-frequency region. In order to illustrate the salient features of the measured and computed results, the radar cross section of a large cylinder (length=5 lambda ) at a bistatic angle of 90 degrees is shown.<>
