A hybrid finite element method is applied to solve the electromagnetic scattering (for both E- and H-polarizations) from coated cylinders. The coating material can be inhomogeneous and have ε and μ different from their free-space values. Three numerical examples are presented to show the validity and versatility of the method: 1) bistatic scattering from a coated circular cylinder, which verifies the formulation and the computer program, 2) backscattering from a coated rectangular cylinder, and 3) backscattering from an ogival cylinder with coated edges. Computations are compared with those obtained using the moment method codes and the exact solutions when applicable.
