    Abstract: The finite difference frequency domain (FDFD) method is very suitable for working out narrowband problems and resonance problems. However, the FDFD method needs to solve a large complex sparse matrix equation. With the increase of computing scale, the dimension of matrix will increase rapidly, which is difficult to simulate. For improving the compu... Show More

    Abstract: The paper considers the problem of calculating the resistance between nodes of infinite grid resistor systems with square and triangular cells. There has long been a question about the resistance between the nearest nodes of an infinite grid of resistances with square cells with the same resistance r. Here, earlier, by the method of symmetry and su... Show More
