Abstract :
The paper presents a hybrid numerical model for simulating electromagnetic scattering from a two dimensional object embedded in multilayered media. The domain is first divided into interior and exterior regions using a cylindrical surface. Finite element formulation is used to solve for the field in the internal region, and the solution of the field is used to find the induced current in the elements that discretize the 2D object. The scatterer is represented as a summation of line sources embedded in multilayered media, and the scattered field is found by summing the contributions from these sources. Simulation results are presented
