  • Publication number: 20020082812
    Abstract: In Moment method, by regarding the current values of a wave source to be constants, the simultaneous equations of the wave source and the simultaneous equations of a receiving object can be separated and the current values of the wave source and the current values of the object can be separately calculated. Even if the positional relationship between the wave source and object changes, the mutual impedance between the elements of the object does not change. Therefore, there is no need to calculate the coefficient matrix of the simultaneous equations of the object again.

  • Patent number: 6185517
    Abstract: An electromagnetic field intensity computing apparatus for computing electromagnetic field intensity of an electric circuit device in a moment method obtains according to the electric current distribution an electric current of a ground layer and models a transmission line, ground layer, dielectric portion, etc. to be analyzed. When a plate to be analyzed is divided into a plurality of patches, the regularity in given structure data is automatically extracted to compute the mutual impedance among a portion of patches and apply the computation result to other portions. When elements to be analyzed meet the conditions that the electric length of the elements is short and the elements are distant from each other, the mutual impedance can be computed in an approximation obtained under various conditions. Furthermore, approximating a portion near a pigtail portion of a coaxial cable using a polygon allows a vertical electric current to be properly connected to each unit.
