Houston TX 77037 U.S.A A new code for modeling electromagnetic fields in complicated 3D environments is based on an integral equation presented in the form used by the Modified Iterative Dissipative Method (MIDM). The integral equation possesses contraction properties that allow the equation to be solved iteratively. A special numerical implementation assures that contraction properties of the equation are preserved
