The characteristics of numerical computation of node unit current model is investigated, and new method for computing integrals of surface patch modeling is presented. Using this method, the pseudosingular point in integral calculation is eliminated, and an efficient technique for computing integral in high frequency condition is provided. The numerical computing technique developed provides theoretical basis for applying the node unit current model to high frequency problems.
