A new approximate model is proposed for the efficient implementation of the electromagnetic scattering and radiation by perfectly electrical conducting (PEC) objects using the method of moments (MOM).In the new model
the PEC object under consideration is divided by two parts
where MOM is performed only on the first part after making a closed-form approximation for the electric current on the second part.Compared with the published hybrid methods
the new model gives better physical explanations.The new model is valid for both two-dimensional and three-dimensional cases.Numerical examples are given for validation of the model.
