Abstract :
A procedure for filling a nested representation of the EFIE impedance matrix is discussed. At low frequencies, the memory complexity of the method is approximately O(N), and the CPU complexity is approximately O(N log N). The reconstruction error is also computed to demonstrate that the fill procedure provides an error-controlled representation over several orders of magnitude.
