High Hc and high Hk has been achieved in FePt films as thin as 70 Angstroms. A channel response matrix is formed between the transmit antennas and the receive antennas to generate a joint channel correlation matrix between the transmit antennas and the receive antennas using a block-FFT decomposition of the channel response matrix. The techniques handle various combinations of conditions resulting in applying style elements to the aggregation before or after applying style elements to underlying artwork. The ratio R of the quantities by volume B3 is higher than 2 and preferably between 2.
