Full Wave Modeling of Array Structures Using Generalized Single-Source Tangential Equivalence Principle Algorithm
The generalized single-source tangential equivalence principle algorithm (GSST-EPA) is proposed to solve the electromagnetic scattering of array structures with very small distance or even connected elements. For the traditional EPA scheme, it is difficult to deal with those situations. Based on sou...

| description | The generalized single-source tangential equivalence principle algorithm (GSST-EPA) is proposed to solve the electromagnetic scattering of array structures with very small distance or even connected elements. For the traditional EPA scheme, it is difficult to deal with those situations. Based on source reconstruction method (SRM), the new GSST-EPA can be used to solve this problem efficiently. This scheme can also reduce the number of unknowns by half via the extinction theorem and keep the good accuracy by using tangential field projection. Furthermore, the multilevel fast multipole algorithm (MLFMA) is used to accelerate the matrix-vector multiplication in the GSST-EPA. Several numerical results are given to demonstrate the accuracy and efficiency of the proposed method. |
