The adaptive integral method is utilized to solve electromagnetic radiation properties of conducting surface/surface configurations. For a complex structure that involves wires and surfaces, a special basis function must be introduced to deal with the rapid varying current distributions. To simplify this model, a uniform RWG basis function has been used to model the surface/surface junction by using a thin strip with no thickness instead of a wire. Then the AIM is employed to accelerate the matrix-vector multiplications and to reduce matrix storage where the full matrices are stored in a sparse form. The preconditioner is developed to decrease the number of iterations and reduce the time of solution. Finally, three numerical examples are presented to demonstrate the accuracy and efficiency of this technique.
