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 nonhomogeneous and have permeabilities and permittivities 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 moment-method codes and exact solutions when applicable
