Abstract :
In this paper, it is discovered that the correlation matrices of antennas whose scattering surface are within the same plane are diagonal matrices. By applying this conclusion to the Numerical Green Matrix Module in the NEC (Numerical Electromagnetic Code), the memory space used by simulation program is significantly reduced, and the computational speed is improved, when the initial structures are face structures within the same plane. In a simulated experiment of NASA ST5 antenna designing, the speed of computation with the method introduced in this paper is 25.3 times faster than that of original NEC, and uses as 1/858 memory as original NEC. Applying the approach to evolutionary antenna research can help with solving one of its great challenges: expensive and time-consuming computation.
