Electromagnetic modelling of curved lossy dielectric surface and cylinder

A new electromagnetic model for curved dielectric surfaces and cylinder has been introduced. The model considers scatterers as a lossy dielectric body. The theoretical and simulation results have been compared with the literature and the model agrees with the published results of the hollow cylinder for which an exact solution exists. Figures of relative error versus ka and kT of hollow cylinder (a) single- (b) three-layered cylinder are used for the parameters. The curved dielectric scatterer is discretised to N small element, and then the contributions of each element are sum up coherently to find the total response. Finally, the simulations for curved cylinder and convex surfaces of arbitrary shape are presented.
