利用不均一分割的FDTD解析程序，为了适应正确表现小型天线的局部部位的细小构造，还有包含电介质材料的电磁场问题而由本研究室开发的解析法。这种解析法可以提高解析效率，并且因为正确表现天线的细小构造，也可以达到提高解析结果精度的目的。-use an uneven division of FDTD analytical procedures, In order to adapt to the correct performance of the local small antenna parts of the small structure, There dielectric material contains the electromagnetic field from the Development Research Center of the analytical method. This analytical method can improve the efficiency analysis, and because the correct performance of a small antenna structure, can achieve greater analytical accuracy of the results.
