A fast algorithm for analysis of the dipole circular array

The conclusion that the generalized impedence matrix and its inverse are both symmetric block circulants with symmetric circulant blocks is obtained by taking into account the symmetry of the dipole circular array, along with a fast algorithm for analysis of that kind of array. It is shown that the time for evaluating the matrix elements is reduced to about 3% that for a normal algorithm with the same precision of the results, with the time for finding the inverse of the matrix reduced to about 25%.
